Colour and Colour theory represents one of the fundamental principles of Graphic Design and Visual Literacy. This site inntroduces some ot the key terms that a designer needs to be aware of when starting to analyse the use of colour and understand the theories and practices involved when discussing colour.
Primary Colors: This definition really depends on what type of medium of color we are using. The colors that are seen when sunlight is split by a prism are sometimes called the spectral colors. These are red, orange, yellow, green, blue, indigo, and violet. These ROYGBIV colors are often reduced to three "red, green, and blue-violet" which are the primary colors for the additive color system (light). The primary colors for the subtractive color system (paint/pigment) are "cyan, magenta and yellow." Notice that "red, yellow and blue" should never be used as the combination for color primaries!
