PSY280H5 Study Guide - Midterm Guide: Subtractive Color, Monochromacy, Color Vision
Document Summary
Hererochromatic light is white light consisting of many wavelengths. Monochromatic light is light consisting of one wavelength. Give an example of two colors that differ with respect to saturation. Hue is the color quality of light (name of color) Additive color mixing is the creation of a new color by a process that adds one set of wavelengths to another set of wavelengths (ex. Coloured flashlights shining together to create new color) Subtractive color mixing is the creation of a new wavelength by the removal of wavelengths from a light with a broad spectrum of wavelengths (ex. Individuals with normal color vision need 3 different wavelengths to match any other wavelength in the visible spectrum. Principle whereby any single cone system is color blind, different combinations of wavelength and intensity can result in the same response from the cone system. Problem is you don"t see as many colors. Single type of cone cannot distinguish color from luminence.
