Colormatica, it's Eromatica's digital book. I'm an artist in Instagram and have decided to make my art available for anyone so you can change the colors of the illustrations to whatever you feel like! Change the skin tone, the hair color, the background color, the nails color, change every single color of my illustrations! Just pick an image, select a color and click wherever you want to change it, that easy. Once you are done, save the illustration in HD to your camera roll and share it with your friends.
