Virtual Cubes

Cube stickers show gradients of the three base colors: red, green and blue. The red color origin is located at corner ulb (up, left, back), while green is at corner rbd (right, back, down) and blue at corner fdl (front, down, left). Base color values decrease monotonically from one origin to the other, which creates new colors. The brightest color is yellow, located at corner urf (up, right, front), while the darkest is black, located at corner dbl (down, back, left).
