For parents
Ages 2+
Pick one of ten crayons, tap a shape, and the shape becomes that colour. Tap it again with a different crayon and it changes again. That is the whole game. There is nothing to complete, no picture it is supposed to end up looking like, and no point at which it tells your child they are done.
No score, no timer, and no wrong answer — a sky coloured brown is not a mistake here. Nothing is saved, so the picture goes when the tab does; if your child wants to keep one, take a screenshot. The ten colours are fixed values rather than the site's own palette, which is what makes red actually red whether your phone is in light or dark mode. Every region is big enough to hit with a thumb on a small screen.
