This coloring page depicts Onyx, a rock type Pokemon. It's huge, with its body made largely of hard, jet-black stone. Onyx has distinctive bright red eyes and a slim, pointed tail. This Pokemon is incredibly robust and is regularly employed in battle. It can even evolve into the much stronger Steelix form. To bring out Onyx's strength and majesty, try to make the stone color appear dark and lustrous, and emphasize the reds for the eyes and tail. Use lighter blues for the shading on the stony body and its curved back, to give depth and interest. Adding some white to the picture could create highlights and make it shine. When coloring Onyx, remember its powerful and unyielding nature.
