Have you ever wondered about colors? There are the natural colors of the visible light spectrum (red, orange, yellow, green, blue, & violet). Then there are seemingly endless variations when these colors are combined. Colors make the world beautiful. Colors also represent moods & attitudes. Green is the 'easiest' color to our eyes. But one might say, "they were green with envy". I've never really seen a green person. Blue colors the open sky and bodies of water.
