Colour Theory

The three basic catergories of colour theory are:  the colour wheelcolour harmony, and the context of how colours are used.

Newton and the Color Spectrum

Modern understanding of light and color begins with Isaac Newton (1642-1726) and a series of experiments that he publishes in 1672.  He refracts white light with a prism, resolving it into its component colors: red, orange, yellow, green, blue and violet.

Sir Isaac Newton’s crucial experiment, 1666-72:  A ray of light is divided into constituent colours by a first prism, and the resulting bundle of coloured rays reconstitute into white light by the second prism.

The Colour Wheel


Colour Harmony Harmony is a noun that describes an agreement, such as in feeling, sound, look, feel, or smell. In visual experiences, harmony is something that is pleasing to the eye. It engages the viewer and it creates an inner sense of order, a balance in the visual experience.
