Document Summary
Light comes down and hits objects: some light is absorbed, some passes through, and some is reflected. Why is the sky blue: light bounces off particles in the sky. Why is the ocean different colors: clear water = not much micro biotic life, dirty water = pollutants, dirt, and other elements within the ocean reflect different colors. Black absorbs all light, white reflects all light. (1) hue: the color itself, 4 real hues: red, blue, yellow, green (primary colors) (2) brightness: the a(cid:373)ou(cid:374)t of white light refle(cid:272)ted off of a(cid:374) o(cid:271)je(cid:272)t"s surfa(cid:272)e if it give- off a lot = less colorful, to measure brightness turn your monitor to black and white (grayscale) (3) saturation: the amount of white light absorbed by an object, strong colors = highly saturated, weak colors = not highly saturated, **color energy is predominately determined by saturation (how strong the color is) Complimentary hues (*concept) *only works with primary colors.
