Coloring books are a quiet evergreen — and every page starts as a prompt. AI Coloring Book Page Prompts hands you 20 copy-paste prompts for crisp, colorist-approved pages: (1–6) fox in the flower garden, butterfly meadow, enchanted castle, mermaid lagoon, gentle dinosaurs and under the sea, (7–12) geometric mandala, hot-air balloons, ice-cream sundae, cozy Christmas tree, cat with sunflowers and rocket to the moon, (13–19) wildflower bouquet, knight and baby dragon, safari scene, woodland tea party, autumn leaves, baby dragon hatching and unicorn meadows — plus (20) a book-cover design prompt. Every prompt ships with tool settings, negative prompt, hook caption and a variation, plus the Line-Art Formula (bold outlines, closed shapes, zero shading) and age presets for toddler, kids and adult books. Kills the two coloring killers: gray shading that ruins print and broken outlines that bleed markers. Built for Midjourney, DALL·E 3, SDXL and Firefly, with a 7-day book-build plan and commercial use included.
