Color and background helpers shouldn’t be used in OUDS Web context please consider using our color modes directly as explained in our background utilities.

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.
