Tips for these
coloring pages
A few things that make these particular pages easier to color and nicer to keep.
The real color order
Red is on the outside of the arc, then orange, yellow, green, blue, indigo and violet. ROY G BIV is the easy way to remember it.
Blend the bands
Let each band overlap the next a little so the colors mix at the edges, the way a real rainbow does. Crayons and colored pencils both blend well.
A rainy day pick
Stuck inside because it's pouring? A rainbow page is the obvious choice, and a good excuse to talk about how sunlight and rain make one.

Frequently asked questions
Everything you need to know about these free coloring pages
Are these coloring pages really free?+
Yes. Print as many as you like for home, classroom or library use. No signup, no email, no watermark.
How do I print a coloring page?+
Click "Print PDF" on any page. The PDF is sized for US Letter with a margin on every side, so you can print it straight away. On A4 paper, pick "Fit to page" in the print dialog.
What paper works best?+
Regular 20 lb (75 gsm) printer paper is fine for crayons and colored pencils. For markers or paint, print on 65 lb cardstock so the color doesn't bleed through.
Which pages are best for little kids?+
The simple pages, with thick lines and big shapes that are easy to stay inside. They're all collected on the "for kids" page. Detailed pages like the mandala have fine lines and many small areas, better for older kids and colored pencils.
Were these pages made with AI?+
Yes. Each page was generated by an AI image model, then cleaned up for printing: pure black lines, a white background and print resolution. The exact prompt is shown with every page.
Can I make my own coloring page?+
Yes. Hit "Use this prompt" on any page and it opens an AI image generator with the prompt filled in. Change the first sentence (the subject) and keep the rest, and you get a new page in the same clean line-art style, free.
Can I sell these coloring pages?+
They're free for personal, classroom and non-commercial use. If you want pages to sell, for example in a KDP coloring book, generate your own from the prompts and check your AI generator's terms for commercial use.
