The chromaticity diagram is produced by plotting 4 X/( X + 15 Y + 3 Z) as abscissa and 6 Y/( X + 15 Y + 3 Z) as ordinate, in which X, Y, and Z are the tristimulus values corresponding to the 1931 CIE Standard Observer and Coordinate System. The use of the following chromaticity diagram is provisionally recommended whenever a diagram yielding color spacing perceptually more nearly uniform than the (xy) diagram is desired.

"Quantitative data and methods for colorimetry". ^ OSA Committee on Colorimetry (November 1944).Document printing is now managed by Imprint's 20+ Wepa printers, and their on-campus poster printing service. The method is to draw the shortest line from the point representing the non-Planckian stimulus to the Planckian locus. As of July 15, 2021, IT Services has retired poster printing (CPLOT) and computer lab document printing. An important application of this coordinate system is its use in finding from any series of colors the one most resembling a neighboring color of the same brilliance, for example, the finding of the nearest color temperature for a neighboring non-Planckian stimulus. "A Maxwell Triangle Yielding Uniform Chromaticity Scales". Digital Pictures: Representation, Compression, and Standards (2E ed.). ![]() The Colorimetry committee of the CIE considered MacAdam's proposal at its 14th Session in Brussels for use in situations where more perceptual uniformity was desired than the (x,y) chromaticity space, and officially adopted it as the standard UCS the next year. (The colors used in this illustration are illustrative only and do not correspond to the true colors represented by the respective points.) u J u d d = 0.4661 x + 0.1593 y y − 0.15735 x + 0.2424 = 5.5932 x + 1.9116 y 12 y − 1.882 x + 2.9088 Judd then translated these isotherms back into the CIEXYZ color space.
