Use color utilities to apply color to the background of elements, text, and borders. These utilities should only be used where color is not provided by a component. To learn more about how to apply color, read the [color documentation](https://primer.style/design/foundations/color) in the [interface guidelines](https://primer.style/design/).

## Text
|
|
|
|
Use text color utilities to set text to a specific color. Color contrast must pass a minimum WCAG accessibility rating of [level AA](https://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html). This ensures that viewers who cannot see the full color spectrum are able to read the text. To customize outside of the suggested combinations below, we recommend using this [color contrast testing tool](https://colorable.jxnblk.com/). For more information, read our [accessibility standards](../principles/accessibility).

<div class="color-fg-on-emphasis color-bg-accent-emphasis p-2 rounded">.color-fg-on-emphasis</div>
|
|
```
|
|
|
|
You can set the color inheritance on an element by using the `color-fg-inherit` class.
|
|
|
|
```html live
|
|
<div class="color-fg-success">This text is green, <a href="#" class="color-fg-inherit">including the link</a></div>
|
|
```
|
|
|
|
## Background
|
|
|
|
Background colors are most commonly used for filling large blocks of content or areas with a color. When selecting a background color, make sure the foreground color contrast passes a minimum WCAG accessibility rating of [level AA](https://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html). Meeting these standards ensures that content is accessible by everyone, regardless of disability or user device. You can [check your color combination with this demo site](https://colorable.jxnblk.com/). For more information, read our [accessibility standards](../principles/accessibility).
