Color Space

Below is one example of using spatial relationships to illustrate how colors may be made by mixing varying intensities of red, green, and blue light. This representation is called a "color space." The percent intensity is based on a linear scale with 0% representing no light of that color to 100% representing the maximum intensity of color that may be measured with a camera or displayed on a computer screen.
