2. What is the difference between adult vs. kids’ coloring books?

Before we begin creating, let’s explore the differences in designing coloring pages for adults versus kids. There are a few key distinctions:

A. Level of detail

  • Adults: Pages tend to be more intricate, featuring numerous small shapes, fine-line artwork, and repeating patterns (think filigree or floral clusters). This encourages focus, mindfulness, and a challenge as they fill in small spaces.
  • Kids: Simpler, bolder shapes with larger areas to color—animals, trucks, basic cartoon scenes—so little hands can stay within the lines and have a quick feel of accomplishment.

B. Line weight & clarity

  • Adults: Thinner lines and minor variations in stroke weight give an elegant, delicate feel.
  • Kids: Thicker, uniform outlines keep the images clear and are forgiving if a crayon drifts outside the edge.

C. Themes and imagery

  • Adults: More sophisticated or abstract themes, like botanical gardens, fantasy landscapes, travel scenes, or Art Deco patterns.
  • Kids: Fun, playful, and familiar subjects, like cartoon animals or simple holiday scenes. 

D. Page layout & composition

  • Adults: Often single-page spreads with repeating motifs or borderless compositions.
  • Kids: More contained scenes (with frames or borders).

E. Cognitive roles

  • Adults: Promotes stress relief, mindfulness, and creative exploration. The “busy” designs help quiet the mind.
  • Kids: Encourages fine motor skills, color recognition, self-expression, and quick wins to keep motivation high.

If you can recognize these differences, you will be able to customize the details, line styles, themes, and layout descriptions for your AI coloring book prompts.

3. How to define your coloring book concept

Begin by clearly defining the theme of your coloring book. This step helps guide all your creative decisions throughout the process.

For adult audiences, consider themes like:

  • Mandalas & geometric patterns
  • Botanical gardens & floral arrangements
  • Intricate animal portraits (e.g. lions, owls, elephants)
  • Zentangles
  • Fantasy worlds (dragons, castles, enchanted forests)
  • Architectural details (Gothic cathedrals, vintage doorways
  • Steampunk & mechanical designs
  • Ocean life & underwater scenes
  • Celestial & astrological themes
  • Cultural motifs (henna-inspired, Art Deco, Aztec patterns)
  • Wine, alcohol, coffee & tea rituals

For children, focus on:

  • Everyday objects and toys
  • Food
  • Fantasy elements
  • Animals
  • Dinosaurs & prehistoric creatures
  • Magical unicorns & fairies
  • Superheroes & sidekicks
  • Outer space adventures (astronauts, rockets, aliens)
  • Vehicles & construction (cars, trains, diggers)
  • Under-the-sea (fish, mermaids, sea turtles)
  • Holiday celebrations (Halloween, Christmas, birthdays)
  • Jungle safari (lions, monkeys, elephants)
  • Cute monsters & robots

Select a theme and create a brief that includes your target audience, artistic style preference, and the overall mood you want to achieve. This will serve as your guiding principle throughout the creation process.

4. How to craft the perfect AI prompt for dynamic coloring pages

When you want AI to generate pages for your printable coloring book, you need to make it feel both dynamic and color-ready. Your prompt needs to be specific, descriptive, and tailored to the AI coloring book generator. Here is what your prompt should include:

1. Audience & complexity

  • Adult: “ultra-detailed”, “intricate”, “fine line art”.
  • Child: “bold outlines“, “simple shapes“, “playful“.

2. Style & line weight

  • Specify “black-and-white vector line art”, “0.3 pt uniform line width“, “no shading”, or “grayscale”.
  • Or “hand-drawn marker style“, “thick outlines“, “thick black outlines“, “clean line art“.

3. Composition & dynamics

  • Adult: Use terms like “dynamic composition”, “flowing movement”, “overlapping elements”, “action lines”, “patterns”, and “textures“.
  • For children: “centered composition”, “isolated objects”, “simple shapes”, “clear white background”, and “recognizable forms”.

4. Theme & motifs

  • E.g. “botanical mandala with swirling vines and hidden animals“.
  • Or “cartoon farm scene: cow, pig, tractor, barn, sun with a smiling face“.

5. Technical requirements

  • Highresolution”, “300 DPI“, “3000×3000 px”.
  • Portrait orientation“, “single-page layout”, “sized for 8.5″×11″ printing”.

6. Negative/exclude notes

  • No shading”, “no text“, “no color“, “no halftones”, “no background noise“.

tip

For items you want to exclude, sometimes it can work better if you simply avoid mentioning them. Experiment with the prompts to see what works for you.

By tailoring every part of your prompt—from the subject and mood to the point size of the lines and the output format—you will get AI-generated coloring pages that match your vision.

What is the formula to craft a rock-solid prompt?

A good prompt =  Technical requirements + Art style + Subject matter + Composition notes + Complexity level + Line quality specifications + Background / Exclude elements or lack thereof.

Example of an adult coloring page prompt

(Technical requirements) “Create a full-bleed A4 format coloring page at 300 DPI + (Art Style) rendered as solid black line art (Subject) a whimsical woodland scene for adults: an ancient oak tree with twisting branches, clusters of mushrooms, hidden woodland creatures, (Composition notes) highly detailed bark texture, stipple shading only. (Line quality) Use a uniform line weight, crisp black outlines (Background / Exclude) on a transparent background, with no shading.

Example of a kids’ coloring page prompt

(Technical requirements) “Create a full-bleed A4 format coloring page at 300 DPI + (Art Style) Simple ink doodle (Subject) of a happy unicorn prancing in a meadow, (Composition notes) big shapes and bold outlines, minimal detail, smiling clouds overhead. (Line quality) 0.5 pt black line width (Background / Exclude) on white background, no text, no background noise.

Perfect Coloring Page Prompt specsPerfect Coloring Page Prompt specsPerfect Coloring Page Prompt specs

What are some pro prompting tips to follow?

  • Avoid clichés: Skip “stress relief mandala”; try “Art Nouveau insect with vine borders”.
  • Words to avoid: GraphicsGen will flag words like “stroke” when referring to line weight. Also, any words that fall in the category of profanity, hate-speech, sexual content, self-harm, terrorism, violence, and other sensitive wordings.
  • Boost detail: Add “cross-hatching”, “stippling“, or “whimsical borders” to prompts.
  • Fix mistakes: If GraphicsGen adds color, use “monochrome line art ONLY” in your prompt.
  • Adult pro tip: Avoid bland art by adding “symmetrical“, “ornate”, or “hidden elements.”
  • Kids pro tip: Use “large shapes”, “bold lines“, “cartoony”, and “playful” to keep it child-friendly.
  • Keep refining: AI art is a process, not a one-and-done task. Learn from each result and tweak your approach accordingly.
  • Create a simple style guide: Record your best prompts, preferred levels of complexity, and design guidelines to maintain consistency.

5. How to generate your first set of adult coloring pages

Adult coloring book prompt 1

Let’s start with coloring book pages for adults. For the sake of this tutorial, we will create different coloring page themes to test out several prompts.

For the first coloring page, select the Adult Coloring Book art style from the GraphicsGen gallery for detailed and intricate designs. GraphicsGen is a great AI line art generator. I chose a 90s nostalgia theme for this concept, featuring items like a Rubik’s Cube and a flip phone, set against a floral background. When writing prompts, pay attention to line weight consistency, the distribution of details, and the overall balance of composition. Here’s an example of an adult coloring page prompt:

  • Create a full-bleed square format coloring page, rendered at 300 DPI as black-and-white solid black line art. In an asymmetrical collage layout, meticulously create highly detailed ’90s icons—a detailed rotary dial telephone, a swirling, bubbly lava lamp, a music cassette tape, a scrambled Rubik’s Cube, and a classic flip phone—interwoven, floating and overlapping an intricate floral arrangement of daisies, sunflowers, and dahlias as a setting. Incorporate negative-space patterns around and between each element to maximize stress-relief coloring. Use a uniform line weight and crisp black outlines on a pure white background, with no shading, no grayscale, no stray dots, or messy linework.

Carefully enter your prompt and click Generate. AI sometimes produces designs with inconsistent line weights or overly complex areas—note these to refine the prompt later. If you find errors, click Generate Another below the rendered image. Correct your prompt and try to generate at least 3-4 different compositions again. Generating multiple works increases the likelihood of finding designs that perfectly match your vision. Once GraphicsGen generates a suitable image, click on the bottom right of the rendered image to download the PNG.

Adult coloring book prompt 2

Keeping the Adult Coloring Book art style selected, an elegant cocktail theme was chosen for the second coloring page. Imagine a martini with a curled lemon twist and olive, a mojito fresh with basil sprigs, and a negroni garnished with a vibrant orange slice—all floating in a playful, asymmetrical layout against a celestial backdrop.

Then I described the intricate cosmic scene, weaving in stars, moons, planets, and swirling filigree to give the page a magical feel. All the outlines must be clean, bold, and black, with no speckles or shading, to maintain a crisp and coloring-friendly appearance. Finally, I ran the prompt. Sometimes the results aren’t perfect, and the prompt must be fine-tuned. Here’s the AI coloring book prompt I worked with:

  • Create a full-bleed square format coloring page, rendered at 300 DPI as black-and-white solid black line art. Create a high-detail adult coloring-book line art page with three floating cocktail glasses arranged in an asymmetrical composition, floating in different angles: A classic martini glass garnished with a long curled lemon twist and a single olive on a pick. A tall mojito glass filled with crisp ice cubes and fresh basil sprigs. A sturdy negroni tumbler featuring a thick orange slice on its rim All suspended over an intricate celestial background of detailed swirling cosmic filigree, planets, crescent moons, stars, and tiny orbs. Use clean, bold black outlines with no shading, or speckles—perfectly crisp for detailed coloring.

Adult coloring book prompt 3

For the third coloring page, I chose a koi and blossom design. I started by locking in the technical specs—”full-bleed square adult coloring book page, 300 DPI, 3 mm bleed“—so the output is print-ready. Next, described my main subjects and their arrangement—“two elegant koi fish swimming in a perfect yin-yang formation, bodies curving into a balanced flow with long tails spinning around.”

Then I nailed down the art style—”intricate hand-drawn pen-and-ink line art, bold crisp black outlines on white, varied line weights for depth, no shading or grayscale.” After that, I layered in the decorative touches—”intertwine lush cherry blossoms (no branches) and fill every inch with dynamic water motifs: ripples, swirls, waves, and bubbles.” Finally, I specify the line work only, excluding any text, to keep the page clean and ready for coloring. So the prompt reads as:

  • Full-bleed square adult coloring book page, 300 DPI, with 3 mm bleed on all sides. Render two elegant koi fish swimming in a perfect yin-yang formation at the center, their bodies curving into a balanced flow and long tails spinning around. Use intricate hand-drawn pen-and-ink line art style: bold, crisp black outlines on a white background, with varied line weights to suggest depth, movement, and scale; no shading or grayscale. Intertwine lush cherry blossoms in different angles, no branches, with individual blossoms floating in the water—adding finely detailed petals around and between the fish. Fill every inch of negative space with dynamic water motifs: ripples, swirling currents, waves, and rising bubbles that organically interact with the fish and floral elements. The composition should flow in a continuous loop around the circle. Exclude any text.”

Another ‘coloring book page for adults’ concept to try is a skull-and-snake motif. I began by locking in the technical specs: “a square format at 300 DPI with a 3 mm bleed—to guarantee a print-ready layout.” Then I defined the focal imagery: “a human skull entwined by two coiling serpents and blooming rose vines.”

Followed by the line specs: “a hand-drawn pen-and-ink vector style with thick, clean black outlines and no shading or grayscale, so it reads as pure line art for coloring.” To keep the page engaging, I requested intricate scale patterns, skull cracks, detailed petals, and hidden death-themed motifs, such as skull-patterned moths and fallen rose petals. Finally, I filled all negative space with swirling, spiky vines plus rose borders, excluded any text or logos, and clarified that the final deliverable should be optimized for pure line work to achieve high-quality print. The prompt reads:

  • Create a square format adult-coloring-book page with 3 mm bleed on all sides, no border, 300 DPI. Feature a central human skull entwined by a large detailed coiling serpent and blooming rose vines. Render entirely in hand-drawn pen-and-ink line art in a bold vector style: thick, clean, black outlines on a white background —no shading or grayscale. Embellish the serpents’ scales, the skull’s cracks, and each rose petal with intricate details. Hide tiny death-themed motifs — moths, dropped rose petals—within the composition’s negative spaces. Fill all empty areas with swirling spikey vines and rose border elements to create a seamless, balanced layout. Exclude any text, brand names, or logos. Output as pure line work optimized for high-quality print.”

For the last concept, I went for a psychedelic vibe. I started as usual, locking in the essentials—a square, single-page layout at 300 DPI with bold, uniform strokes and no shading—to guarantee a crisp, print-ready result. From there, I defined the overarching vibe as an “immersive psychedelic tapestry”.

I broke it into five layered motif groups (ribbons & spirals, mandala details, organic surreal elements, micro-patterns, and Op-Art panels), each described with vivid verbs (twist, evolve, weave). By spelling out how ribbons morph into fractal spirals, mandalas into interlocking petals, and vines into alien blossoms, the prompt ensures that every negative space is filled with dots, dashes, or checkerboard waves. Finally, I reiterated the need for clean, continuous lines edge-to-edge so that the design remains both seamless and sharply defined. A prompt example:

  • “Create a single-page, square-format adult coloring book illustration at 300 DPI in crisp black line art with uniform thick strokes and no shading. Fill the entire page edge-to-edge with an immersive psychedelic tapestry: -Flowing Ribbons & Spirals: Draw fluid, ribbon-like shapes that twist and merge in an endless dance, evolving into fractal spirals and kaleidoscopic mandalas. -Mandala Details: Each spiral unfolds into concentric rings and petals, their geometry intricate and interlocking, inviting close coloring. – Organic Motifs: Weave in strange fungi, twisting vines, and alien blossoms—some bearing hidden faces or symbols—to add a surreal, living quality. – Micro-Patterns: Fill negative spaces with delicate dots, dashes, concentric circles, and tiny stars to encourage detailed work. – Op-Art Elements: Integrate checkerboard waves, moiré ripples, and optical-illusion panels that pulse with movement. Ensure all lines are clean, continuous, and bold enough for precise coloring.”

6. How to create the children’s versions using the Simple Ink Doodle Style

Switch to the Simple Ink Doodle art style for kids’ coloring pages. It’s also an excellent option for AI line art generation. Since we will focus on simplicity and bold shapes for this age group, the Simple Ink Doodle style is ideal for creating clean, streamlined designs that are perfect for children. When creating prompts for children’s coloring pages, concentrate on the following elements:

  • Large, clearly defined spaces for coloring
  • Minimal details
  • Clear subjects
  • Positive, friendly images

Kids’ coloring book prompt 1

Begin by locking in the page specs—a single-page, square format at 300 DPI—to guarantee a crisp, print-ready canvas. Then define the star of the scene (a dynamic, galloping unicorn with a long, flowing mane and tail) and surround it with playful motifs (swirling ribbons, blooming flowers, fluttering butterflies, twinkling stars, bubbling hearts, and bows) to fill every corner with energy.

Next, specify a hand-drawn pen-and-ink vector style—thick, clean black outlines with varied line weights and no shading—to keep the artwork pure line work for easy coloring. Finally, I excluded any text or branding to ensure the illustration stands independently. The prompt reads: 

  • Create a single-page, square-format kids’ coloring-book illustration at 300 DPI. Center a dynamic galloping cartoon unicorn with a long flowing mane and tail. Surround it with long swirling ribbons, blooming flowers, fluttering butterflies, twinkling stars, bubbling hearts, and bows to fill the scene with playful energy. Render entirely in hand-drawn pen-and-ink line art in a crisp vector style: thick, clean black outlines on a white background with varied line weights to convey motion and depth—no shading or grayscale. Exclude any text, brand names, or logos. Optimize as pure line work for easy coloring.”

Kids’ coloring book prompt 2

For the second coloring page, let’s do an astronaut theme. First, set down the print requirements—a single-page, square layout at 300 DPI—for color-ready art. Next, define the main character of the scene: a young astronaut ‘surfing’ on a rocket board through a vibrant galaxy.

To spark imagination, the background should be filled with oversized, easy-to-color planets, smiling faces, playful comets, and friendly aliens waving from asteroids. To keep it kid-friendly, every element should be rendered in bold, hand-drawn line art, with thick, crisp outlines of varied weights and no shading. Fun, chunky details such as planet faces, gear buttons, and comet flares will add charm, along with broad, open spaces for coloring. Finally, make sure to exclude any text or branding from the design. The prompt should read something like this:

  • Create a single-page, square-format kids’ coloring-book illustration at 300 DPI. Feature a dynamic scene of a young astronaut surfing on a rocketboard through a vibrant galaxy: the astronaut boy in a simple, cartoon-style spacesuit, arms outstretched, streaming in zero gravity. Surround them with large, easily colorable planets, smiling stars, playful comets with trailing tails, and two or three friendly alien characters waving from nearby asteroids. Render all elements as bold, hand-drawn line art: thick, crisp black outlines on a white background, with varied line weights for emphasis but no shading or grayscale. Include fun, chunky details—planet faces, gear buttons, and comet flares—while leaving broad open areas for coloring. Exclude any text, brand names, or logos.”

Kids’ coloring book prompt 3

For this sample, let’s work on animal characters. We’ll specify a square format at 300 DPI and then build out the scene: two cute animal characters (a cat baker in a chef’s hat and apron behind a pastry-filled window, and a dog server in a bow tie holding a steaming cup) set before a simple café façade.

Display pastries, a blank chalkboard menu, and some potted flowers. Ensure you include thick, clean outlines on a transparent background with no shading or grayscale, allowing for pure line art that facilitates easy coloring. For the background, add simple trees and bushes, and exclude any text.

  • Create a square-format, 300 DPI, hand-drawn line-art illustration for a children’s coloring book featuring two cute animal characters in front of a cozy café storefront: – Characters: – A friendly cat baker wearing a chef’s hat and apron, standing behind store window panel with cupcakes, loaves of bread, and pastries. – A cheerful cartoon dog waiter in a bow tie and server apron, holding a tray with a steaming cup and saucer. – Setting: – A quaint café façade with a striped awning, large display window showing baked goods, a small chalkboard menu (blank for coloring), and potted flowers on either side of the door. Coffee Table upfront . – Style: – Thick, clean black outlines on a transparent background. – No shading or grayscale—pure line art for easy coloring. – Extras: – Leave the café sign and chalkboard blank. Tree and bush background within the page borders. – Exclude any text, logos, or branding.

Kids’ coloring book prompt 4

For sample four, a Japanese culture theme was chosen. I began crafting this prompt by setting the essentials—a single-page layout at 300 DPI. Next, I centered the scene around a kawaii kitten in a simple floral kimono behind a sushi counter.

I added clear, chunky kitchen props (rice bowls, bamboo steamer, soy dish, sushi board, and fish accents) and a charming Japanese wall pattern in the background to create context. I specified uniform 1 pt black line art with smooth, rounded strokes and no shading to keep everything bold and kid-friendly, and left generous white space. Finally, I framed it all with a thick inner border set 3 mm from the edge to tie the composition together. This is the AI coloring book prompt:

  • Design a single-page, square-format coloring book illustration at 300 DPI. Center a kawaii cartoon kitten in a simple floral kimono with tied obi, standing behind a sushi counter. One paw holds a bamboo rolling mat while the other shapes rice into nigiri. Surround the foreground scene with chunky, easy-to-color kitchen props—bowls of rice, a bamboo steamer, a soy-sauce dish, a wooden sushi board, and plate of fish. In the background, a kawaii cherry blossom Japanese-style wall design. Render all elements in uniform 1 pt black line art with clean, rounded strokes and no shading. Leave ample white space and simple pattern. Finish with a thick line border set 3 mm inside the page edge.”

Here is a fun approach with skeletons. I sketched out the playful concept: three bubbly skeleton characters enjoying a sunny beach day, each engaged in a fun activity (digging with a shovel, tossing a beach ball, splashing in gentle waves) to set a lighthearted, dynamic mood.

Next, I added simple seaside accents—scattered shells, a sand bucket, starfish on the shore, a palm tree bending in the breeze, and a smiling sun overhead—to frame the scene. Finally, I finalized the style guidelines: bold, uniform 1-point black outlines with no shading and clear, open shapes, ensuring the line art remains clean, accessible, and perfectly suited for children.

  • Create a single-page, square-format adult coloring book illustration at 300 DPI. A cheerful kids’ coloring-book page in clean black-and-white line art features three bubbly cartoon skeletons enjoying a sunny beach day. One skeleton enthusiastically digs in the sand with a small shovel; another is joyfully playing with a beach ball and splashes in gentle waves: and the third building a sandcastle. Surround them with simple, whimsical seaside details—scattered shells, a sand bucket, starfish on the sand. Add a palm tree bending in the breeze, and a smiling sun overhead. Use bold, uniform 1 pt strokes with no shading, keeping shapes clear and open. Lay out all elements on a single page with plenty of white space for coloring.
