This is a volcano coloring page, and it is made for both experienced and beginners. That is, you can colorize it in a complex way, as in the example below, or in a simpler way.
A volcano, like a mountain, can be covered with grass, ground, stones or sand. In the example from Coloringpagez.com, you can see a rather gloomy, gray and rocky volcano.
The smoke itself emerging from the bowels of the volcano should be painted in different shades of gray. Do not forget to paint shadows and light areas on the volcano and the cloud of smoke.
