Chromatic value= hue + tone + saturation 


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!


Secondary colours result from the mixing of two of the primary colours. Red (magenta) and yellow produce orange, yellow and blue (cyan) produce green while red and blue (cyan) produce violet. For example, if you add more red than yellow, you get a reddish orange, and if you add more yellow than red, you get a yellowish orange.
