We just learned about the Pupil black circle in the eye.
Another part of the eye is the Iris.
The iris is the part of the eye with color.
Most eyes are either brown or blue, but they can be other colors like green, hazel, grey or red.
Remember that the pupil is just a hole that lets light in to the eye to see.
The iris has the muscles that make the pupil bigger or smaller.
