The color constancy of 5 normal and 10 red‐green color deficient (4 protanopes, 3 deuteranopes, 3 deuteranomalous trichromats) observers was investigated by an achromatic matching task, in which they were required to adjust the color of a central patch within a scene until it appeared as a neutral gray. The patch was presented in the middle of a CRT Mondrian display, which was initially set to CIE Illuminant C or D65 and then shifted along either the red‐green cardinal axis, blue‐yellow cardinal axis, or Planckian locus. Despite their significantly higher red‐green discrimination thresholds, color deficient observers display color constancy similar to that of normal observers along all three axes. However, their variability is greater for settings along the red‐green cardinal axis. © 2000 John Wiley & Sons, Inc. Col Res Appl, 26, S209–S213, 2001
