Mixbox is a new blending method for natural color mixing. It produces saturated gradients with hue shifts and natural secondary colors during blending. Yellow and blue make green. The interface is simple - RGB in, RGB out. Internally, Mixbox treats colors as real-life pigments using the Kubelka & Munk theory to predict realistic color behavior. That way, colors act like actual paints and bring more vibrance and intuition into digital painting.
