Abstract

Color information such as a combination of fundamental colors in the subtractive or additive color mixing, hue, chroma and value in the psychological attributes of color, or coordinate values in a uniform color space are transformed nonlinearly and mutually by using a neural network, particularly a multi-layered feedforward neural network sufficiently trained of the transformation on samples of known data.
