Bootstrap: customize theme colors

Bootstrap provides a few default color variables. For example, Bootstrap 5.2 (the latest at the time of writing) provides the following colors:

$blue:    #0d6efd !default;
$indigo:  #6610f2 !default;
$purple:  #6f42c1 !default;
$pink:    #d63384 !default;
$red:     #dc3545 !default;
$orange:  #fd7e14 !default;
$yellow:  #ffc107 !default;
$green:   #198754 !default;
$teal:    #20c997 !default;
$cyan:    #0dcaf0 !default;

You can find these in scss/_variables.scss. To override them, you can do something like this:

// Required
@import "../node_modules/bootstrap/scss/functions";

// Default variable overrides
$body-bg: #000;
$body-color: #111;

// Required
@import "../node_modules/bootstrap/scss/variables";
@import "../node_modules/bootstrap/scss/maps";
@import "../node_modules/bootstrap/scss/mixins";
@import "../node_modules/bootstrap/scss/root";

// Optional Bootstrap components here
@import "../node_modules/bootstrap/scss/reboot";
@import "../node_modules/bootstrap/scss/type";
// etc
