You can play with the duckling coloring, and see how the image when it is painted. Duck suit, even on a small clipart.
Coloring in a raster (pixel) format. If you use a graphics editor such as adobe Photoshop, then using the fill can easily paint a picture. Outlines for coloring perfect to spend some time coloring on the computer. For children this can be fun and not an obsessive study of the work in the graphic editors, and knowledge of the world in different shades and colors.
