In humans, there are two types of light-sensitive receptors in the eye – cones and rods. Cones transmit a color image to the brain, while rods transmit only a monochrome (black and white) image. But cones only work well in good lighting conditions. On this day and in bright light, the brain uses the information from the cones and we see the world in color. And at dusk and in low light, the brain “switches” to the image transmitted by the sticks and we see an almost black-and-gray world.
