-## Colors
-
-Colorize text with color utilities. If you want to colorize links, you can use the [`.link-*` helper classes]({{< docsref "/helpers/colored-links" >}}) which have `:hover` and `:focus` states.
-
-{{< example >}}
-{{< colors.inline >}}
-{{- range (index $.Site.Data "theme-colors") }}
-<p class="text-{{ .name }}{{ with .contrast_color }} bg-{{ . }}{{ end }}">.text-{{ .name }}</p>
-{{- end -}}
-{{< /colors.inline >}}
-<p class="text-body">.text-body</p>
-<p class="text-muted">.text-muted</p>
-<p class="text-white bg-dark">.text-white</p>
-<p class="text-black-50">.text-black-50</p>
-<p class="text-white-50 bg-dark">.text-white-50</p>
-{{< /example >}}
-
-{{< callout warning >}}
-**Deprecation:** With the addition of `.text-opacity-*` utilities and CSS variables for text utilities, `.text-black-50` and `.text-white-50` are deprecated as of v5.1.0. They'll be removed in v6.0.0.

-## Opacity
-
-{{< added-in "5.1.0" >}}
-
-As of v5.1.0, text color utilities are generated with Sass using CSS variables. This allows for real-time color changes without compilation and dynamic alpha transparency changes.
-
-### How it works
-
-Consider our default `.text-primary` utility.
-
-```css
-.text-primary {
-  --bs-text-opacity: 1;
-  color: rgba(var(--bs-primary-rgb), var(--bs-text-opacity)) !important;
-}
-```
-
-We use an RGB version of our `--bs-primary` (with the value of `13, 110, 253`) CSS variable and attached a second CSS variable, `--bs-text-opacity`, for the alpha transparency (with a default value `1` thanks to a local CSS variable). That means anytime you use `.text-primary` now, your computed `color` value is `rgba(13, 110, 253, 1)`. The local CSS variable inside each `.text-*` class avoids inheritance issues so nested instances of the utilities don't automatically have a modified alpha transparency.
-
-### Example
-
-To change that opacity, override `--bs-text-opacity` via custom styles or inline styles.
-
-{{< example >}}
-<div class="text-primary">This is default primary text</div>
-<div class="text-primary" style="--bs-text-opacity: .5;">This is 50% opacity primary text</div>
-{{< /example >}}
-
-Or, choose from any of the `.text-opacity` utilities:
-
-{{< example >}}
-<div class="text-primary">This is default primary text</div>
-<div class="text-primary text-opacity-75">This is 75% opacity primary text</div>
-<div class="text-primary text-opacity-50">This is 50% opacity primary text</div>
-<div class="text-primary text-opacity-25">This is 25% opacity primary text</div>
-{{< /example >}}
-
-## Specificity
-
-Sometimes contextual classes cannot be applied due to the specificity of another selector. In some cases, a sufficient workaround is to wrap your element's content in a `<div>` or more semantic element with the desired class.
-
-## Sass
-
-In addition to the following Sass functionality, consider reading about our included [CSS custom properties]({{< docsref "/customize/css-variables" >}}) (aka CSS variables) for colors and more.
-
-### Variables
-
-Most `color` utilities are generated by our theme colors, reassigned from our generic color palette variables.
-
-{{< scss-docs name="color-variables" file="scss/_variables.scss" >}}
-
-{{< scss-docs name="theme-color-variables" file="scss/_variables.scss" >}}
-
-Grayscale colors are also available, but only a subset are used to generate any utilities.
-
-{{< scss-docs name="gray-color-variables" file="scss/_variables.scss" >}}
-
-### Map
-
-Theme colors are then put into a Sass map so we can loop over them to generate our utilities, component modifiers, and more.
-
-{{< scss-docs name="theme-colors-map" file="scss/_variables.scss" >}}
-
-Grayscale colors are also available as a Sass map. **This map is not used to generate any utilities.**
-
-{{< scss-docs name="gray-colors-map" file="scss/_variables.scss" >}}
-
-RGB colors are generated from a separate Sass map:
-
-{{< scss-docs name="theme-colors-rgb" file="scss/_maps.scss" >}}
-
-And color opacities build on that with their own map that's consumed by the utilities API:
-
-{{< scss-docs name="utilities-text-colors" file="scss/_maps.scss" >}}
-
-### Utilities API
-
-Color utilities are declared in our utilities API in `scss/_utilities.scss`. [Learn how to use the utilities API.]({{< docsref "/utilities/api#using-the-api" >}})
