Why Are There Colors?

Why Are There Colors?

Sunlight may appear to be white, but it is actually a mixture of all the colors that can be seen in a rainbow – red, orange, yellow, green, blue, and violet. When white light hits an object, some of the colors are absorbed and some are reflected. The reflected colors are the ones that we see.

The petals of a red flower absorb most of the colors of the white light that shines on it, reflecting the red rays. Therefore, red is all we are able to see. A yellow flower absorbs all of the colors but yellow. A white flower reflects almost all of the colors back to our eyes.

Our eyes are formed of structures that transmit electrochemical impulses when they are impacted by energy in specific wavelength (energy) ranges. How our brain perceives these different impulses is what we call color.

Color is simply a perceptual phenomenon that has developed, apparently, to take advantage of the differential response of light energies when interacting with matter. Color is one way our brain identifies energy in the surrounding environment.
