It is good to give the child to paint a picture from memory, or paint in the opposite color sample, for example, when there is a ready-made picture of a night scene, but the child should paint the daily events of the same characters, etc.
If while coloring your child goes out of the outline, it will not be so noticeable. When the child sees how cool his result is, it will inspire confidence in him and will be a good stimulus for further work. Good coloring are those with the text in it. The text introduces the kid with the game, the kid will be interesting, while the text will expand its horizons.
