Modern computers make use of colour in various ways:
- User interfaces use colour to provide visual hints to users, and to make the application more appealing.
- Websites use colour for similar reasons, and also to make adverts and products for sale more attractive.
- We use computers to take photographs, edit them, and print them.
- Similarly we use computers to design or draw graphics and art.
- We shoot, edit and watch videos and movies on computers.
- Computer games would be pretty boring without colour.
In this series we will look at how computers represent colour:
- Light and colour - a basic overview colour in the real world, and how the human eye sees colour.
- RGB colour - colour is most commonly represented as red, green and blue values, which is described here.
- Other colour spaces - other colour spaces such as CMYK and HSL are covered here.
- Colour depth - how colour is represented in binary.
- Transparency - coming soon.
- Image compression - coming soon.
- Image file formats - coming soon.
- Colour management - coming soon.
