I found this amazing infographic that contains a whole slew of insightful and eye-catching information on 'Color Theory' (of all things). Pretty handy for graphic designers (and animators?)
But first, a brief outline of what Color Theory actually is (thanks Wikipedia!)
Wikipedia defines Color Theory as:
a body of practical guidance to color mixing and the visual impacts of specific color combination. There are also definitions (or categories) of colors based on the color wheel: primary, secondary and tertiary colors. Although color theory principles first appeared in the writings of Leone Battista Alberti (c.1435) and the notebooks of Leonardo da Vinci (c.1490), a tradition of "colory theory" began in the 18th century, initially within a partisan controversy around Isaac Newton's theory of color (Opticks, 1704) and the nature of so-called primary colors. From there it developed as an independent artistic tradition with only superficial reference to colorimetry and vision science.
