if black is all colors and white is no colors what is gray?
In: 1072
An important thing to remember is that color is mostly psychological. Our eyes have sensors that detect a very specific range of the electromagnetic spectrum, and our brains interpret those signals as colors.
We have three types of cones in our eyes that sense three different ranges of wavelengths of light. *Very approximately* speaking, you can say that we have red, green, and blue sensors in our eyes. And our brains interpret different combinations of those signals as colors. If our blue and red sensors are most stimulated, our brain says, “That’s purple!” If our red and green sensors are stimulated, “That’s yellow!”
And if all of our sensors are about equally stimulated? Well, that’s no color. If there’s no color and it’s dark (not a lot of light hitting our eyes) then it’s black. If there’s no color and it’s bright (a lot of light hitting out eyes) then it’s white. Somewhere in between is gray.
