Color Wheel
The 12-part Color wheel is a representation of the visual spectrum of light that us humans can actually see. It is the rainbow we see through the dispersion of white light through prisms and raindrops. The visible spectrum (traditional ROYGBIV) is a very small range of the whole electromagnetic spectrum that runs from radio waves on the long end to Gamma waves on the short end. Each color has a specific wave frequency that our eyes perceive as different color sensations. The basic color groupings that concern artists are the Primary colors (3), the Secondary colors (3), and the Tertiary colors (6). Hue refers to the color name, as in red, blue, and yellow are different hues. Color saturation is to the strength of color as it is presented. Chroma is the amount of grayness in a color, achieved my adding white or black. Value refers to a color's lightness or darkness on a gray scale of 1 to 10.
