Color and background

Set a background color with contrasting foreground color.

Overview

Color and background helpers combine the power of our .text-* utilities and .bg-* utilities in one class. Using our Sass color-contrast() function, we automatically determine a contrasting color for a particular background-color.

Heads up! There’s currently no support for a CSS-native color-contrast function, so we use our own via Sass. This means that customizing our theme colors via CSS variables may cause color contrast issues with these utilities.

Accessibility tip: Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies like screen readers. Please ensure the meaning is obvious from the content itself (e.g., the visible text with a sufficient color contrast) or is included through alternative means, such as additional text hidden with the .visually-hidden class.

With components

See Bootstrap examples that are incompatible with Orange Design System.

These variants should not be used because they do not respect the Orange Design System specifications.

Use them in place of combined .text-* and .bg-* classes, like on badges:

Primary Info 
<span class="badge text-bg-primary">Primary</span>
<span class="badge text-bg-info">Info</span>

Or on cards:
