Colors
Bootstrap 5 Colors
MDB is supported by an extensive Material Design color system that themes our styles and components. This enables more comprehensive customization and extension for any project.
Theme
We use a subset of all colors to create a smaller color palette for generating color schemes,
also available as Sass variables and a Sass map in Bootstrap’s
scss/free/_variables.scss file.
All these colors are available as a Sass map, $theme-colors in
scss/free/_variables.scss file.
$theme-colors: (
"primary": $primary,
"secondary": $secondary,
"success": $success,
"info": $info,
"warning": $warning,
"danger": $danger,
"light": $light,
"dark": $dark
);
Note: Theme colors are also available as CSS classes. You can use them directly in your project without compiling scss code. Have a look at the examples below.
Background
Easily set the background by using .bg-* color classes
<div class="bg-primary"></div>
<div class="bg-secondary"></div>
<div class="bg-success"></div>
<div class="bg-danger"></div>
<div class="bg-warning"></div>
<div class="bg-info"></div>
<div class="bg-light"></div>
<div class="bg-dark"></div>
<div class="bg-white"></div>
<div class="bg-transparent"></div>
Background gradient
By adding a .bg-gradient class, a linear gradient is added as background
image to the backgrounds. This gradient starts with a semi-transparent white which fades out to the bottom.
Do you need a gradient in your custom CSS? Just add background-image: var(--mdb-gradient);.
<div class="p-3 mb-2 bg-primary bg-gradient text-white">.bg-primary.bg-gradient</div>
<div class="p-3 mb-2 bg-secondary bg-gradient text-white">.bg-secondary.bg-gradient</div>
<div class="p-3 mb-2 bg-success bg-gradient text-white">.bg-success.bg-gradient</div>
<div class="p-3 mb-2 bg-danger bg-gradient text-white">.bg-danger.bg-gradient</div>
<div class="p-3 mb-2 bg-warning bg-gradient text-dark">.bg-warning.bg-gradient</div>
<div class="p-3 mb-2 bg-info bg-gradient text-dark">.bg-info.bg-gradient</div>
<div class="p-3 mb-2 bg-light bg-gradient text-dark">.bg-light.bg-gradient</div>
<div class="p-3 mb-2 bg-dark bg-gradient text-white">.bg-dark.bg-gradient</div>
Text
Colorize text with color utilities.
.text-primary
.text-secondary
.text-success
.text-danger
.text-warning
.text-info
.text-light
.text-dark
.text-body
.text-muted
.text-white
.text-black-50
.text-white-50
<p class="text-primary">.text-primary</p>
<p class="text-secondary">.text-secondary</p>
<p class="text-success">.text-success</p>
<p class="text-danger">.text-danger</p>
<p class="text-warning bg-dark">.text-warning</p>
<p class="text-info bg-dark">.text-info</p>
<p class="text-light bg-dark">.text-light</p>
<p class="text-dark">.text-dark</p>
<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>
Depracation: With the addition of .text-opacity-* utilities and CSS variables for text utilities,
.text-black-50 and .text-white-50 are deprecated as
of Bootstrap v5.1.0. They’ll be removed in v6.0.0.
Links
You can use the .link-* classes to colorize links. Unlike the
.text-* classes, these classes have a :hover and
:focus state.
<a href="#" class="link-primary">Primary link</a>
<a href="#" class="link-secondary">Secondary link</a>
<a href="#" class="link-success">Success link</a>
<a href="#" class="link-danger">Danger link</a>
<a href="#" class="link-warning">Warning link</a>
<a href="#" class="link-info">Info link</a>
<a href="#" class="link-light">Light link</a>
<a href="#" class="link-dark">Dark link</a>
Some of the button styles use a relatively light foreground color, and should only be used on a dark background in order to have sufficient contrast.
Components
We also use theme colors as predefined colors for some components, for example, buttons.
<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-secondary">Secondary</button>
<button type="button" class="btn btn-success">Success</button>
<button type="button" class="btn btn-danger">Danger</button>
<button type="button" class="btn btn-warning">Warning</button>
<button type="button" class="btn btn-info">Info</button>
<button type="button" class="btn btn-light">Light</button>
<button type="button" class="btn btn-dark">Dark</button>
Opacity
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.
.text-primary {
--mdb-text-opacity: 1;
color: rgba(var(--mdb-primary-rgb), var(--mdb-text-opacity)) !important;
}
We use an RGB version of our --mdb-primary (with the value of 13, 110, 253) CSS variable and attached a second CSS variable,
--mdb-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 --mdb-text-opacity via custom styles or inline styles.
<div class="text-primary">This is default primary text</div>
<div class="text-primary" style="--mdb-text-opacity: .5;">This is 50% opacity primary text</div>
Or, choose from any of the .text-opacity utilities:
<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>
Background
To change that opacity, override --mdb-bg-opacity via custom styles or inline styles.
<div class="text-primary">This is default primary text</div>
<div class="bg-success p-2 text-white">This is default success background</div>
<div class="bg-success p-2" style="--mdb-bg-opacity: 0.5;">This is 50% opacity success background</div>
Or, choose from any of the .bg-opacity utilities:
<div class="bg-success p-2 text-white">This is default success background</div>
<div class="bg-success p-2 text-white bg-opacity-75">This is 75% opacity success background</div>
<div class="bg-success p-2 text-dark bg-opacity-50">This is 50% opacity success background</div>
<div class="bg-success p-2 text-dark bg-opacity-25">This is 25% opacity success background</div>
<div class="bg-success p-2 text-dark bg-opacity-10">This is 10% opacity success background</div>
Full palette
All MDB colors are available as Sass variables and a Sass map in
scss/free/_variables.scss file. To avoid increased file sizes, we don’t create
text or background color classes for each of these variables. Instead, we choose a subset of
these colors for a theme palette.
Be sure to monitor contrast ratios as you customize colors. As shown below, we’ve added three contrast ratios to each of the main colors—one for the swatch’s current colors, one for against white, and one for against black.

Generating utilities
Bootstrap doesn’t include color and background-color utilities for every color variable,
but you can generate these yourself with our utility API and our extended Sass maps added in v5.1.0.
- To start, make sure you’ve imported our functions, variables, mixins, and utilities.
- Use our
map-merge-multiple()function to quickly merge multiple Sass maps together in a new map. - Merge this new combined map to extend any utility with a
{color}-{level}class name.
Here’s an example that generates text color utilities (e.g., .text-purple-500) using the above steps.
@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/mixins";
@import "bootstrap/scss/utilities";
$all-colors: map-merge-multiple($blues, $indigos, $purples, $pinks, $reds, $oranges, $yellows, $greens, $teals, $cyans);
$utilities: map-merge(
$utilities,
(
"color": map-merge(
map-get($utilities, "color"),
(
values: map-merge(
map-get(map-get($utilities, "color"), "values"),
(
$all-colors
),
),
),
),
)
);
@import "bootstrap/scss/utilities/api";
This will generate new .text-{color}-{level} utilities for every color and level. You can do the same for any other utility and property as well.
