+
+## Overview
+
+{{< added-in "5.2.0" >}}
+
+Color and background helpers combine the power of our [`.text-*` utilities]({{< docsref "/utilities/colors" >}}) and [`.bg-*` utilities]({{< docsref "/utilities/background" >}}) in one class. Using our Sass `color-contrast()` function, we automatically determine a contrasting `color` for a particular `background-color`.
+
+{{< callout warning >}}
+**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.

+
+{{< example >}}
+{{< text-bg.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<div class="text-bg-{{ .name }} p-3">{{ .name | title }} with contrasting color</div>
+{{- end -}}
+{{< /text-bg.inline >}}
+{{< /example >}}
+
+## With components
+
+Use them in place of combined `.text-*` and `.bg-*` classes, like on [badges]({{< docsref "/components/badge#background-colors" >}}):
+
+{{< example >}}
+<span class="badge text-bg-primary">Primary</span>
+<span class="badge text-bg-info">Info</span>
+{{< /example >}}
+
+Or on [cards]({{< docsref "/components/card#background-and-color" >}}):
+
+{{< example >}}
+<div class="card text-bg-primary mb-3" style="max-width: 18rem;">
+  <div class="card-header">Header</div>
+  <div class="card-body">
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+  </div>
+</div>
+<div class="card text-bg-info mb-3" style="max-width: 18rem;">
+  <div class="card-header">Header</div>
+  <div class="card-body">
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+  </div>
+</div>
+{{< /example >}}
