The Colour of Light: Additive colour theory
Primary Colours of Light Red, green, and blue are called the primary colours of light The primary colours of light cannot be created from other colours The primary colours of light combine to form all other colours of light and white light red green blue
Secondary Colours of Light Yellow, cyan, and magenta are called the secondary colours of light Each secondary colour is formed when two primary colours of light combine yellow cyan magenta
red green yellow
blue green cyan
red blue magenta
Additive Colour Theory The additive colour theory states that: White light is formed by combining the three primary colours of light Secondary colours of light are formed by combining two primary colours of light
Complementary Colours of Light Complementary colours of light are any two colours that produce white light when mixed together The three pairs of complementary colours of light are: blue and yellow red and cyan green and magenta
Applications Computer monitors, TV screens, digital cameras use the additive colour theory to capture or display fullcolour images TV screens and computer monitors are made up or rows of pixels There are red, green, and blue subpixels Different combinations of subpixels are illuminated to display all the different colours you see on your television
