Abstract
Masking of red, green, and blue dotted alphabetic characters (of about 0.34 cd/m2) by random dots of the same colors and luminance indicates that masking is greatest with red masking dots and red-dotted target patterns, and least with blue masking dots and targets. Over-all masking increases as mask-to-target interval increases and as the number of masking dots increases, but varying dot luminances down to about 0.034 cd/m3 have relatively little effect on the amount of masking. A major difference between colors occurs, however, only when there is an interval between target and mask. Color differences are also greatly reduced when the spectral bandwidth is reduced. These findings are interpreted in terms of time-constant differences among the mechanisms that mediate human color vision.
