Color Contrast Best Practices

Color Contrast Tools

There are many free color contrast tools available on the internet. Here are a few that I’ve used that you may find helpful:

UTA’s official color identity information is readily available. The official UTA orange does not provide sufficient contrast with white; Marketing, Messaging and Engagement has specified color code C45517 as the approved orange alternate for electronic body text or EF6E0B for electronic large text for webpages. Note, these are not approved for print materials. 

Contact University Communications for assistance with printed materials, as color contrast may continue to be an issue.

Whenever possible, we suggest that you use orange only as decorative elements. The same would hold true for the use of green, yellow or red, as these are particularly difficult for those with colorblindness. If you must use a shade of orange, green or red, be extra careful to ensure that you are reaching the required contrast ratio.

If you need any assistance with determining if you have reached sufficient contrast, please contact us at We will be glad to assist you!

Accessibility – habit, not hindsight!
