Some Quantitative Aspects of an Opponent-Colors Theory II Brightness, Saturation, and Hue in Normal and Dichromatic Vision

Key Points

• This research aims to develop a quantitative model for understanding color perception based on opponent-colors theory.
• Utilized CIE color mixture data for the standard observer.
• Examined spectral brightness, saturation, and hue for both normal and dichromatic vision.
• Focused on Bezold-Brücke hue shift and discrimination changes with luminance.
• The model effectively accounts for spectral brightness and associated psychophysical functions.
• Findings indicate variations in hue and saturation with different luminance levels.
• The study clarifies the Bezold-Brücke hue shift mechanism.
