Choosing the right colours

Always ensure that people who cannot perceive colour or see it in a different way can still understand the information.

If you need to use colour to convey information make sure that colour-blind safe colours are used. Use a colour-blind simulator, such as Vischeck, to test your colours to see whether they are colour-blind safe.

Colour palettes should be chosen to maximise the difference in perception between the colours and also appear distinct to people with varying types of colour blindness.

A good starting point is to choose colours that are distinct from the background and each other.

When choosing a colour palette tools like Colorbrewer can provide a good starting point. Palettes for use in the ONS will be added here in the future.
