In the past, I've had help when it comes to color. Recently, I've taken greater interest in the process and I'm wondering what techniques are out there, especially for adding tone to animation (matte, paint, something else?). If it helps, I'm using Toon Boom Harmony.
So what is your question or request about color? I found a excellent book, who title I can not remember just now, that covers a lot about color theory.
