A new color-difference formula based on uniform color-difference space presented. CIELAB color space that was revised seemed to create an equal color difference between the adjacent hue lines or chroma lines on the Munsell system. Weighting functions for a new chroma scale and new hue-difference scale adjust the distance in uniform space to the perceived color-difference magnitude of the Munsell system. We called this uniform space a uniform color-difference space. We determined the total color-difference between two color samples with the weighting factor corresponding to the location of the color samples in uniform color-difference space. The Relationships between the total color-difference used in the new formula and the perceived magnitude were performs analyzed through visual perception data sets. The new formula is better than CIELAB, CIE94, and CIEDE2000.
