title: Detection threshold for lights of varying purity.
abstract: Duration thresholds for hue substitution stimuli of various wavelenghts and colorimetric purity were determined. Results indicated an inverse relationship between duration thresholds and colorimetric purity. It was also found that short-wavelength sensitive (SWS) cones can contribute to the detection of low purity, short duration (less than 5 ms) stimuli.
