Clouds running across the sky, driven by uncontrollable wind like white ships sent to the round-the-world cruise, they swim gracefully majestically across the blue sky. Mutate under the action of air flow, they are in no place. Merry them the way. Let the wind whisk them to obediently ground. Paint and create your interesting bizarre contours of clouds.
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.
Coloring can be printed, and then paint.
