For example, long wavelength colors like red may stimulate arousal and increase attention. This model proposes that biological responses to color (e.g., physiological responses such as increased heart rate or attention) are driven by color's embodied meaning; The model also considers that influencers of color experience do not act in isolation.
The RGB color model, therefore, is a convenient means for representing color but is not directly based on the types of cones in the human eye. The peak response of human cone cells varies, even among individuals with so-called normal color vision; [8] in some non-human species this polymorphic variation is even greater, and it may well be adaptive.
The colors in each pair oppose each other. Red-green receptors cannot send messages about both colors at the same time. This theory also explains negative afterimages; once a stimulus of a certain color is presented, the opponent color is perceived after the stimulus is removed because the anabolic and catabolic processes are reversed. For ...
The opponent process is a color theory that states that the human visual system interprets information about color by processing signals from photoreceptor cells in an antagonistic manner. The opponent-process theory suggests that there are three opponent channels , each comprising an opposing color pair: red versus green , blue versus yellow ...
From a physiological point of view, the LMS color space describes a more fundamental level of human visual response, so it makes more sense to define the physiopsychological XYZ by LMS, rather than the other way around. A set of physiologically-based LMS functions were proposed by Stockman & Sharpe in 2000.
Humans are sensitive to light with a short wavelength. Specifically, melanopsin is sensitive to blue light with a wavelength of approximately 480 nm. [19] The effect this wavelength of light has on melanopsin leads to physiological responses such as the suppression of melatonin production, increased alertness, and alterations to the circadian ...

The color spectrum clearly exists at a physical level of wavelengths (inter al.), humans cross-linguistically tend to react most saliently to the primary color terms (a primary motive of Bornstein's work and vision science generally) as well as select similar exemplars of these primary color terms, and lastly comes the process of linguistic ...
