How to use this prompt
For kids' coloring pages, "bold thick black outlines" and "closed shapes only" matter more than realism. This prompt keeps the rocket friendly rather than technical so it appeals to ages 3–8. If Flux adds internal panel lines that are too fine, add "minimal interior detail." The 4:5 ratio prints nicely on standard letter paper with margins.
Variations to try
- Dinosaur theme — swap rocket for "friendly cartoon dinosaur with spots and a volcano in background"
- Underwater scene — replace space with "submarine, fish, and bubbles" keeping the same bold-outline rules
