+description: Set a background color with contrasting foreground color.
+group: helpers

+
+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`.

+{{< 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 >}}
+
+Use them in place of combined `.text-*` and `.bg-*` classes, like on badges:
+
+{{< example >}}
+<span class="badge text-bg-primary">Primary</span>
+<span class="badge text-bg-info">Info</span>
+{{< /example >}}
+
+Or on cards:
+
+{{< example >}}
+<div class="card text-bg-primary mb-3" style="max-width: 18rem;">
+  <div class="card-header">Header</div>
+  <div class="card-body">
