A sustained complementary hue may be obtained with a rotating black-white disc and pulses of chromatic light. Effects of disc rotation speed and of the chromaticity and luminance of the color pulse are described. The disc, observed at 11 speeds from 10 through 110 cps had a black and white sector. At the sector boundary there was an aperture through which red, yellow, green, blue, or purple light (filters equated for luminous transmittance) was pulsed for 3% of each cycle, followed by the white half cycle. Eleven observers made Munsell matches (total: 4995) to these lights, which were presented at three luminances. Complementary matches occurred 48% of the time, matches similar to the hues of the projected lights—33%, neutral matches—19%. There were systematic hue shifts around two pairs of stable points in the hue circle, as functions of disc rotation speed. The predominance of complementary matches over similar-hue matches varied with color-pulse chromaticity and luminance, and with discspeed.
