Coloring this Sonic X coloring page is a great way to bring the adventure home! His bright blue hue makes him stand out against the green hill and yellow sun. Start by coloring his white head, black eyes and mouth. His triangular ears can be a deep orange for a fun contrast. His thin body can be shaded a few shades darker than his head. His red sneakers make a nice pop of color and should be filled in with a bright red. White socks and a hint of a light brown for his skin would make an interesting texture when mixed together. The green hill could be colored a couple shades of various greens and the yellow sun could be a nice light yellow. Finish the page off with highlights of lighter shades to add more dimension.
