The effect of flash durations of 5 milliseconds (msec.), 500 msec., and 5 seconds on a color naming technique was examined in a dark –field Maxwellian View optical system. Although the results showed variability among three subjects in most regions of the spectrum, all subjects were tested and showed to be part of the population for normal color perception. Graphical interpretation was made for the average of all subjects. There was little indication that color naming shifted, although there are indications of hue purity increases with flash duration. In portions of the spectrum there is an increase in saturation from 5 msec. to 500 msec. and a decrease in saturation from 500 msec. to 5 sec.
