In a companion paper [Perez-Carpinell et al., Color Res Appl 2001;26:158-170], for a set of seven color references, we compared the methods of simultaneous and memory color matching by 15 protanomals and 21 deuteranomals, looking for differences between them and a group of 25 normal trichromat observers investigated previously [Perez-Carpinell et al., Color Res Appl 1998;23:234-247]. In our current article, matching times of the same anomalous trichromat groups, and with the same reference tests, to select from among the comparison chips the one that most resembled one of the seven reference tests, have been measured under simultaneous and successive color matching procedures. From comparison between both anomalous groups and the group of 25 normal trichromats, we can deduce the following results: (1) Matching time depends significantly on the test color both for simultaneous and memory color matching; (2) in simultaneous matching, normal trichromats are faster and deuteranomals are slower; (3) in memory color matching, deuteranomals are slower and normal protanomals are equally fast; and (4) ratio of matching time for both modes of presentation is notable between deuteranomals and normals for dark orange, light green, and pink.
