The Effects of Set Size on Color Matching Using CRT Displays

In: Human factors: the journal of the Human Factors Society, Band 28, Heft 1, S. 49-61

Abstract

The time required to match a colored stimulus to one of a set of colors was measured as a function of color sets ranging in size from 2 to 10. Reaction time (RT) increased linearly with increases in set size to 5 or 6, after which the increase, although still linear, was less steep. Error rate increased sharply with set sizes of 8, 9, and 10. The relative RTs to the different colors remained constant despite changes in the experimental method.
