  • Title: Asymmetries in the time-course of chromatic adaptation and the significance of contrast.
    Author: Werner A, Sharpe LT, Zrenner E.
    Journal: Vision Res; 2000; 40(9):1101-13. PubMed ID: 10738069.
    Abstract:
    The time-course of chromatic adaptation was determined as a function of the spectral content of the adaptation-light and of image-contrast. The adaptation-lights varied along the chromatic cardinal axes or one of their intermediate axes in an equiluminant plane in colour-space. We found an asymmetry in the initial time-course of adaptation (0.2-10 s) in that adaptation to middle-wavelength light was significantly faster than adaptation to short- and long-wavelength light. The asymmetry was only observed in the presence of a spatially complex pattern. It was fully supported by luminance and chromatic contrast and present under haploscopic stimulus conditions.
