Document Summary

He thought that our perception of color came from the way we process the world. Experiement: he cut a whole in a wall and pass light through a prism (which creates a rainbow). Then he focused the light into the tiny whole so that only a small portion of light can come through. The he wanted to gure out if he could break down the single color (green). There are pure lights, which cannot be broken up into composite colors. These are lights that cannot be broken down into further rainbows. Newton"s idea was that white light was a mixture of pure lights (7, he thought). However, there is no discrete number of pure lights. De ning color on the color solid: we can break down the multiple dimensions of color, which varies across 3 dimensions. Hue: the quality that distinguishes the different color categories (red, green, blue ). Saturation: quality of dominance of hue in the color.
