Answer:

The cones detect the brightness and the rods the colors.

Step-by-step explanation:

Thanks to a layer of photoreceptors inside the eye, it is able to convert the captured light into brain signals.

There are two types of photoreceptors: rods and cones.

Rods: they allow the human eye to have a visual acuity (the eye's ability to resolve and perceive small details in an object) and to differentiate colors.
Cones: are in charge of detecting the intensity of the light. They are very numerous and are very sensitive. Not being able to distinguish colors, they give rise to an achromatic vision.
