1. The Colour of Light:
Additive colour theory

2. 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

3. 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

4. red
green
yellow

5. blue
green
cyan

6. red
blue
magenta

7. 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

9. 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

10. Applications
Computer monitors, TV screens, digital cameras use the additive colour theory to capture or display full- colour 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
