Abstract

According to the properties and distribution of Macadam ellipses on the CIE1931 (x, y), a new uniform chromaticity diagram named (U, C) obtained by using the coordinate translation and non-linear compression along radius direction with the aid of the iterative algorithm. Compared with CIE 1931 (x, y), the uniformity of (U, C) is obviously improved. Moreover, it appears to perform as well as or better than these chromaticity diagrams in the IPT and CIECAM02-UCS color spaces.
