  7. Does everything required to understand...

Does everything required to understand the content have a contrast ratio of at least 3:1 against their background?


Ensure that people can visually identify the content.

Why this matters

If the contrast isn’t high enough for all the users to be able to read a chart or infographic, then the chart or infographic fails to achieve its purpose.

How to implement


Read Using color, specifically the section on charts and infographics.
