The color the eye sees in a occurrence depends on which cells are stimulated. Blue light, instead of model, stimulates the blue-sensitive cones, which the brain subsequently interprets as blue. The brain interprets combination of responses from multiple cones by one time and secondary ensign are seen as a consequence. For model, red light and blue light stimulate both the red cones and blue cones, correspondingly, and the brain interprets this combination as magenta. Which combination relating red plus blue. If all three types of shaft cells are stimulated by an equal amount of light, the eye go to see white or more or less neutral shade of aged.
Cones are more reach unfashionable in the eye than rods. Also, they are much excluding light responsive, so they are not even enthusiastic but for the brightness of a occurrence or object is away from a individual threshold. The consequence is with the aim of low light conditions lean to look monochromatic like black and white, but brighter measures are detected by the cones and in consequence seen in bursting color.
