Each type of cone contains a distinctive type of pigment: one cone absorbs red light, another absorbs green, and the third type blue-violet light. Emitted or reflected/absorbed light of a given color stimulates all three types of receptors with varying effectiveness, and the pattern of these responses determines which color is perceived by the brain, which in turn recognizes four psychological primary colors (blue, yellow, red, and green). colors primaris físics physical primary colors (traducció pendent) 2026-03-30 20:24:10
