Dynamics of Color Category Formation and Boundaries
Dynamics of color boundaries is broadly the area that characterizes color categorization as a process that occurs over time.
A color category boundary is the area in perceptual color space where the labeling of one color transitions into another label. Color is a continuous wavelength dimension but distorted into nonlinearly perceived perceptual categories. A category boundary is fundamentally a distortion of continuous color space during perceptual and cognitive processing of color. There is no external signal in the wavelength dimension to tell the perceptual system to make this abrupt transition. This is called the problem of invariance . The demarcation of color space has led to empirical work seeking to characterize color boundaries and discover their underlying dynamics.
