What you will get

A black-and-white colouring page from your photo, with bold clean outlines, no shading, large open areas and simplified details suited to the age you chose.

Why it works

Colouring pages need bold outlines, no shading and big open spaces, so the prompt asks for all three on white. The age blank sets how much detail to keep: simple shapes for young children, finer ones for adults. Keeping the subject recognisable makes it a page from your own photo.

Common mistake

The lines are thin and too many.

Fix: Say “thick outlines, no more than about 15 main shapes, no tiny patterns”, especially for a five-year-old.

Also watch for

Grey shading or filled black areas appear. Add “pure white inside every shape, no grey, no solid black fills”. Check the print on paper before making copies.
The subject becomes unrecognisable. Name what must stay, such as “our dog’s floppy ears and the front door”, and use a photo with a clear simple subject.

Try a variation: make an adult version

Switch the age to adult and add “fine detail, mandala-style patterns inside the larger shapes”. You get a more relaxing page from the same photo.

Keep the same composition. Make the outlines thicker, remove the background clutter and make each shape big enough for a crayon.
