How Much Do You Know About Color Perception?

Understanding Color Perception

• Perception is based on inferences made from photons bouncing off surfaces and entering our eyes.
• The process of perception involves reception, transduction, and coding of information in the brain.
• The retina contains photoreceptors called rods and cones, which are responsible for detecting light and color.
• Rods are sensitive to dim light, while cones are responsible for color vision and are concentrated in the central part of the retina.
• Visible light is the part of the electromagnetic spectrum that our eyes can detect, with the human eye most sensitive to light in the green range.
• Trichromatic theory proposes that there are three types of cones in the human eye, responding to different wavelengths of light, which can produce all colors of the spectrum.
• Opponent Process theory suggests that color perception is based on three opponent processes and that red-green and blue-yellow are perceived as mutually exclusive.
• Color constancy is the tendency for a surface to appear the same color despite changes in the wavelengths contained in the illuminant.
• The brain helps us to construct what color surfaces probably are in real life, and perception is a constructive process.
• There is a top-down influence on color perception, even from very low-level processing of color.
• Color perception is a complex process that involves both photoreceptors and neurons in the brain.
• Our perception of color is not entirely driven by the wavelengths of light that hit the retina, but rather a constructive process that involves multiple factors.
