Using 24 observers with normal color vision, perceived shifts in hue w
ere determined for a yellow-red, green, and blue-green at intermittenc
ies of 5, 10, and 20 cps. The hue shift for yellow-red was consistent
with the hue shift exhibited by a deuteranomalous observer while the h
ue shift for green and blue-green was consistent with that exhibited b
y a protanomalous observer.
