Coloring Page Prompt: ChatGPT Line Art Page From Your Idea

Prompt

Act as a coloring book illustrator who writes image prompts for printable coloring pages, keeps every outline bold and closed so crayons stay inside the lines, and matches the amount of detail to the colorer's age.

Inputs:
- The scene or subject, with the exact count of each object: [PageSubject]
- Who will color it (age group or adult): [AgeGroup]
- Detail level: big simple shapes, medium, or intricate: [DetailLevel]
- Page size and orientation: [PageSizeAndOrientation]
- Border or frame: [BorderStyle]
- Things to leave out: [AvoidList]

Generate:
1. The image prompt, ready to paste into ChatGPT's image generation: subject with exact counts, pure black outlines on a plain white background, line weight for AgeGroup, no shading, no gray fills, no textures, closed shapes, the page orientation from PageSizeAndOrientation, and the BorderStyle.
2. A simpler variant with fewer, bigger shapes, for a younger colorer or a second try.
3. A "leave out" line built from AvoidList plus the usual problems: text, letters, signatures, color, gradients, crosshatching.
4. A print check of five yes or no questions the user can answer by looking at the image (counts, closed outlines, white background, no gray, margins).
5. A one-line fix to send as a follow-up if the image fails a check.

Rules:
- Keep the subject list short enough to count. Every object in the prompt gets an exact number.
- No copyrighted characters, brands, or real people.

Instructions

Fill in the brackets and run it in ChatGPT, Claude, or Gemini to get the image prompt, then paste that image prompt into ChatGPT's image generation (or another image tool you use). Check the result against the checklist before printing. Do not ask for copyrighted characters or real people, and only sell pages if the image tool's terms allow it.

1. IMAGE PROMPT
A printable children's coloring page in landscape orientation, black line art on a plain white background. One friendly cartoon turtle sitting on a flat rock in a pond, with a simple patterned shell made of large shapes. Three round lily pads floating on the water. One dragonfly flying in the sky.

No shading, no gray, no fills, no textures. One plain black rectangle border around the whole page with a white margin outside it.

2. SIMPLER VARIANT
A landscape coloring page for young kids: one big cartoon turtle on one rock, three lily pads, one dragonfly. Extra thick black outlines on white, very large shapes, almost no small details, one plain rectangle border.

3. LEAVE OUT
No words, letters, title, signature, or numbers. No other animals. No color, gradients, gray shading, crosshatching, or background texture.

4. PRINT CHECK
- Is there exactly one turtle, three lily pads, and one dragonfly?
- Are all outlines closed, with no gaps a crayon could leak through?
- Is the background pure white with no gray areas?
- Is there one plain rectangle border with space before the paper edge?
- Are there no letters or words anywhere?

5. FIX IF IT FAILS
"Same page, but [the failed check, e.g. remove the gray shading on the water and make every outline solid black and closed]."

Paste the image prompt from step 1 into ChatGPT's image generation, check the result with step 4, and print on plain US Letter paper in landscape.
