When considering the arrangement of rods and cones in the retina, there is a central location where only cones are found. As we move farther away from this point there are increasing amounts of rods and fewer cones so, as some point we are only able to see black and white. This central location of only cones is known as the

Fovea centralis

Explanation:

The fovea centralis is also a part of the structures found in the eyes.

The fovea centralis is characteristics as a small, central pit made up of closely packed cones and no rods in the eye.

It is found in the center of the macula lutea of the retina. It is the location that has the highest visual acuity and best color vision.
