Phototransduction: conversion of light energy into neural impulses that brain can understand. Colors we see may not actually be what we see. Green is a contrast our brain made up, becomes consistent when our brains comes into constant contact with it. Colors can look more vibrant as we turn up the brightness. Adding primary colors of light creates other colors, such as yellow. Where all the colors overlap, the color is white, this is the surface where all colors are reflected.
