Forward monitor model using multiple non- square matrices M N , M R , M G, M B are 3x11matrices trained with only colors from Neutral, Red, Green, and Blue classes, respectively. During the training process, only M N is set constraint to map exactly RGB XYZ for white color.

– Step 1: For a given RGB, compute r, g, and b. – Step 2: Compute the p, q coordinates on the pq plane. – Step 3: Color cube is classified on the pq plane Haneishi’s color classification method RGB Plane R+G+B=const
