Abstract

CIE technical committee TCl-47 was established with a goal to improve the performance of the CIE94 color-difference equation. Recent visual experiments indicated that a hue-angle dependency might exist. Four datsets focused on hue differences were used to derive a new hue-angle function. The resulting function resulted in a statistically significant improvement compared with existing color-difference equations.
