Which part of the human eye is sensitive to red, blue, and green light? 

The retina is the eye's innermost layer. It is light-sensitive and functions as a camera film. 

There are three layers of neural cells in them: ganglion, bipolar, and photoreceptor cells. It transforms a picture into electrical nerve impulses that the brain may perceive. 

The retina is the eye's screen. The retina contains photoreceptors such as rods and cones. As a result, it is colour-sensitive.
