Colour and Constrast

What to do

Ensure that colour is not the only means of conveying information.

Use sufficient contrast for text and background colours.

Avoid white backgrounds.

Do not use colour solely for decoration.

Be aware of colour blindness.

How to find it

To find insufficient colour contrast, use the Accessibility Checker.

You can also look for text in your document that’s hard to read or to distinguish from the background.

Avoid placing text over images.

Why do it

People who are blind, have low vision, or are colour-blind might miss out on the meaning conveyed by colours alone so use other distinguishing factors too.

If your document has a high level of contrast between text and background, more people can see and use the content.

How to do it

Use accessible text colour

Use accessible text format

Tools for checking colour and contrast

Webaim Contrast Checker

Colour Blindness Simulator
