The present study considers a fuzzy color system in which three membership functions are constructed on a color triangle. For a given fuzzy input, this system outputs the center of gravity of three weights that are associated with respective grades. Three fuzzy sets (red , green , and blue) are applied to the color triangle relationship. By evaluating the attributes of redness, greenness, and blueness, a target color can be easily obtained as the center of gravity of the resulting fuzzy set. The output of the system is a tone triangle, which includes a compound vector with three weights (scalars) in color space. The difference between a fuzzy input and the resulting inference output is shown by the input-output characteristic ( leg shape) between the redness of the input and the chromaticness of the output. Shape effects of conical fuzzy set are investigated.
