Build your own colour key

Drag colours into the key below (or just tap them). The first colour becomes number 1, the next number 2, and so on. Then choose a picture and every number takes your colours.

Your key (0)

Drop colours here to start your key.

If a picture has more numbers than your key, the extra numbers keep their original colours.
