PHO-2052 Chapter Notes - Chapter 5: Subtractive Color, Additive Color, Color Theory
Document Summary
Colors describe not only the emotional world within us but also the physical world through science. The brighter the light, the better you will be able to distinguish between colors. An object"s surface will absorb either all or part of rays of light, producing a perception of a specific hue. We refer to colors in light and colors in pigments, as in paint, in the same ways, although they do not have the same behavioral characteristics. Sir isaac newton discovered a way to see the spectrum of visible light using a prism to refract white light. Wavelengths are measured in nanometers, or billionths of a meter. The region of red has the longest wavelengths, from 625 to 740 nanometers. Violets have the shortest wavelengths, somewhere around 400 nanometers. Wavelengths that are invisible to the human eye lie above and below the visible spectrum. Newton brought the ends of the color spectrum together to conceive the color circle.
