PPT-Human Color Perception By: Lisa Wieczorek

Eric King Humans perceive color when light enters the eye and is detected by the photoreceptors called cones which are mainly located in the fovea We have trichromatic color vision which means we have three different kinds of cones that detect a specific wavelength of light namely short blue medium green and long red How we perceive color also depends on how dim or bright the light is .
