Have you ever wondered why your eyes see colors the way they see them? Have you ever asked yourself, “Does my friend see orange the same way I see orange?” The way our eyes perceive color is a fascinating phenomenon.
The Physics Side To Perceiving Colors
You may have learned this long ago in physics class, but here’s a quick refresher on how colors are created. First, light hits an object and the object reflects back a certain wavelength of that light. Red surfaces, for example, absorb all the colors except red which is reflected back... hence the color “red”.
The Biological Side To Perceiving Colors
Our eyes use photoreceptors called cones to see colors. Different cones are activated by different light wavelengths. When cones are stimulated, they send signals to the brain’s visual cortex which processes all the information and pieces together a color image (in a fraction of a second). Amazing!
