Accessible Color

Ensure a strong color contrast between foreground and background on every document, slide and web page. Always use color plus another visual indicator (for example, color plus boldface type or color plus size to communicate important information.

 

Don't use color alone to convey meaning

Don't use color alone to make a distinction, a comparison or to set something off or apart from the rest of the web page. If you categorize something by color alone, those who are color blind or blind will not benefit from the color distinction.

 

Use sufficient color contrast

If you print your color graphic on a black and white printer, would it be understandable? Without sufficient color contrast, people who are color blind will not be able to benefit from the information.
