摘要: Publisher Summary This chapter discusses other phenomena of color vision. It also the fundamental problem discrimination between two lights, specified in terms chromaticity and intensity, differing dominant wavelength, colorimetric purity, or a combination these. A complete study thresholds for would involve comparisons all visible colored lights their neighbors 3-dimensional solid. The presents classification defective vision such as dichromats, monochromats, anomalous trichromats. appearance physical light spectral composition is not always same; it depends, to some extent, on whole pattern stimulation reaching retina, previous stimulations. factors that cause identical have different appearances under conditions.
