How Do We See Things And Know What Color They Are?

Let’s start with light. Light can be broken up into a few colors: red, orange, yellow, green, blue, indigo, and violet! When we see white light coming from the Sun or a lightbulb, that white light is all of the rainbow colors together. When the white light hits an object it reflections, or bounces of the object, or gets absorbed by the object. Reflection is when light bounces off a surface. Did you know that every time you see something, light is reflecting off the thing you are looking at! Light can bounce off smooth surfaces in a much orderly way and you can see your reflection on the surface, like a mirror or pond! Absorption is when light gets absorbed by the thing it is hitting. The 7 colors of light get absorbed or reflected by some on objects. The colors that are reflected by the object are what we see! Inside of our eyes, there are specific cells that sense three wavelengths or colors of light: red, blue, and green. Believe it or not, these three types of cells can sense all of the colors of the rainbow. When they sense specific colors, they send a message to our brain, telling us what color an object is!!
