When it strikes a coloured object this colour. When light from the banana hits the cones it stimulates them to varying degrees. How Do We See Colors But the reflection and refraction of light on an object is just one part of the story.

In a white object we see the color white as all the light is reflected whereas in black it absorbs all the wavelengths. The first one has to do with our moodemotions. You see the banana as yellow.

The retina makes color vision possible by essentially acting as a light sensor. That reflected light enters the eye where the lens focuses it toward cones and rods. Each type respond to different wavelengths of light.

Another 2 respond strongest to blue light. One of the psychologists involved in the. The cones and rods react to the light and encode it into signals that the brain can read.

The cones then send a signal along the optic nerve to the visual cortex of the brain. We can see Yellow by catching the wavelength that directly corresponds to the color or by catching both Red and Green at the same time. For example orange is seen as reddish-yellow while turquoise is seen as greenish-blue.

The brain then perceives those signals as color. Short wavelengths stimulate blue cones. Long wavelengths stimulate red cones.

These signals get sent to the brain through a complex network of neurons and synapses. Red green and blue are the additive primary colors of the color spectrum. How Do We See Color We See Color Thanks To Specialized Receptors In Our Eyes Eye Facts Human Anatomy And Physiology Eye Exercises.
