Short-flash Bezold-Brucke hue shifts.
Hue matching was used to obtain measures of Bezold-Brucke hue shifts with very brief flashes (17 msec) at ten wavelengths and several illuminance levels. Results were generally similar to those obtained by Purdy (1931) with uncontrolled stimulus duration. but there were also important differences. These were: the locations of invariant hues; the direction of shift for blue-green hues: and a rev...
متن کاملHue discrimination, unique hues and naming.
The hue discrimination curve (HDC) that characterizes performances over the entire hue circle was determined by using sinusoidally modulated spectral power distributions of 1.5 c/300 nm with fixed amplitude and twelve reference phases. To investigate relationship between hue discrimination and appearance, observers further performed a free color naming and unique hue tasks. The HDC consistently...
متن کاملBezold–Brucke hue-shift as functions of luminance level, luminance ratio, interstimulus interval and adapting white for aperture and object colors
UNLABELLED For spectral and nonspectral aperture color 3 s stimuli, Bezold-Brucke (B-B) hue-shift was measured for one to six subjects for four functions: (1) luminance (L) level from 0.1:1.0 through 100:1000 cd/m2; (2) L ratio from 1:2 through 1:1000; (3) illuminant color temperature (for seven illuminants including A and D65) by two adaptation methods; and (4) interstimulus interval from 0 th...
متن کاملRod influence on hue-scaling functions
Rod influence on hue appearance of spectral lights was characterized by comparing the scaling of red, green, yellow, and blue hue sensations for an 8 degrees-diameter, 7 degrees-eccentric test spot under conditions that minimized (cone plateau) and maximized (dark adapted) rod influence at two mesopic light levels (1.5 and 3.0 log scoptic trolands). At the lower light level, the hue-scaling fun...
متن کاملHue shifts produced by temporal asymmetries in chromatic signals.
Observers viewed M- or L-cone-isolating stimuli and compared slowly-on and slowly-off sawtooth waveforms of the same mean chromaticity and luminance. Between 6 and 13 Hz, the mean hue of slowly-on L-cone and slowly-off M-cone sawtooth flicker appeared redder, and the mean hue of slowly-off L-cone and slowly-on M-cone sawtooth stimuli appeared greener-despite all the waveforms' having the same m...
