As a matter of fact, @mojacookie doesn’t even need a green colored pencil, as she can mix that color from her even severely pared-down palette of just red, blue, and yellow.
And don’t miss this awesome colored pencil illustration of Hatsune Miku from earlier this year! Casey can’t draw Pokémon no matter how many colored pencils you give him, but you can follow him on Twitter anyway.
Those colors also correspond with the four available starter Pokémon in the games: fire-type Charmander, grass-type Bulbasaur, water-type Squirtle, and electric-type Pikachu.
You can find more of @mojacookie’s artwork on her Niconico Douga account, her Pixiv account, and her Instagram account.
