Use color utilities to apply color to the background of elements, text, and borders.

## Text colors
2020-10-09 05:04:22 +03:00
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).

2020-10-19 10:49:57 +03:00
> ⚠️ The `.color-text-warning` currently doesn't pass accessibility standards, but will be updated in the future. **Use with caution**.

2018-12-07 22:07:42 +03:00
You can set the color inheritance on an element by using the `text-inherit` class.

```html live
2020-10-19 10:49:57 +03:00

```

## Background colors
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).

You can inverse the canvas background color. Be sure to also inverse the text color (`.color-text-inverse`) to give enough contrast.
2020-10-19 10:49:57 +03:00
```html live
<div class="color-bg-canvas-inverse color-text-inverse mb-2">.color-bg-canvas-inverse .color-text-inverse</div>
2020-10-29 03:09:07 +03:00
```
When using the functional inversed background colors the `.color-text-white` is the better choice as it keeps the text white in all color modes. An exception is the `.color-bg-warning-inverse`.
```html live
<div class="color-bg-info-inverse color-text-white mb-2">.color-bg-info-inverse .color-text-white</div>
<div class="color-bg-success-inverse color-text-white mb-2">.color-bg-success-inverse .color-text-white</div>
2020-10-19 10:49:57 +03:00
<div class="color-bg-warning-inverse mb-2">.color-bg-warning-inverse</div>
2020-10-29 03:09:07 +03:00
<div class="color-bg-danger-inverse color-text-white mb-2">.color-bg-danger-inverse .color-text-white</div>
2020-10-19 10:49:57 +03:00
```
## Border colors
Override default border colors with the following utilities.
```html live
<div class="border color-border-primary mb-2">.color-border-primary</div>
<div class="border color-border-secondary mb-2">.color-border-secondary</div>
<div class="border color-border-tertiary mb-2">.color-border-tertiary</div>
<div class="border color-border-info mb-2">.color-border-info</div>
<div class="border color-border-success mb-2">.color-border-success</div>
<div class="border color-border-warning mb-2">.color-border-warning</div>
<div class="border color-border-danger mb-2">.color-border-danger</div>
<div class="color-bg-canvas-inverse color-text-inverse p-3">
<div class="border color-border-inverse">.color-border-inverse</div>
</div>
```
### Borders with alpha transparency
> TODO: Deprecate?
Use `border-black-fade` to add an rgba black border with an alpha transparency of `0.15`. This is useful when you want a border that tints the background color. The shade of black we use matches the hue of the GitHub dark header and our gray color palette: `rgba(27,31,35, 0.15)`.

2019-08-13 00:50:38 +03:00
```html live
2020-10-19 10:49:57 +03:00
<div class="border border-black-fade color-bg-info p-2 mb-2">.border-black-fade</div>
<div class="border border-black-fade color-bg-danger p-2 mb-2">.border-black-fade</div>
```
On dark backgrounds use `border-white-fade` instead. It adds an rgba white border with an alpha transparency of `0.15`. Or use `.border-white-fade-xx` to add a white border with various levels of alpha transparency.
```html live
<div class="color-bg-info-inverse color-text-inverse p-3">
<div class="border-bottom border-white-fade-15 p-2 mb-2">
.border-white-fade-15 or .border-white-fade
</div>
<div class="border-bottom border-white-fade-30 p-2 mb-2">
.border-white-fade-30
</div>
<div class="border-bottom border-white-fade-50 p-2 mb-2">
.border-white-fade-50
</div>
<div class="border-bottom border-white-fade-70 p-2 mb-2">
.border-white-fade-70
</div>
<div class="border-bottom border-white-fade-85 p-2 mb-2">
.border-white-fade-85
</div>
