Unable to override $theme-color in bootstrap

It's bootstrap 4.0 with SASS

My style.scss file contains the following code:

@import "../bootstrap/scss/bootstrap";

@import "colors";
@import "main";

and _colors.scss file contains the following code:

$bg-white : white;

$theme-colors: (
        primary: #333333
)

You can see that I am just trying to override the $theme-color('primary') but the problem is this that it does nothing.

And If I shift @import "colors" in the start of the file style.scss It gives me following error:

error ../bootstrap/scss/_forms.scss (Line 284: $color: null is not a color for `rgba')

Actually, the style.scss file compiles to style.css file and that one is linked file.

Question: How I can override the $theme-color in bootstrap-4 when using SASS?

Any help will be appreciated, and Thanks in advance

Cheers.

Update 2021 for Bootstrap 5

Per the guidance in the docs...

"Variable overrides must come after our functions are imported, but before the rest of the imports."

Therefore, overriding the theme-colors in Bootstrap 5 works the same way as 4.x. In order to override the theme-colors, simply change appropriate theme color variable before importing bootstrap.scss

/* custom.scss */
/* change theme colors */
$primary: #362ec4;
$secondary: #8f5325;
$success: #3e8d63;
$info: #7854e4;
$warning: #b8c924;
$danger: #d62518;
/* end custom.scss */

@import '~bootstrap/scss/bootstrap.scss';

Update 2018 for Bootstrap 4.1

To change the primary, or any of the theme colors in Bootstrap 4 SASS, set the appropriate variables before importing bootstrap.scss. This allows your custom scss to override the default value, and will then be set in all the theme-colors loops (btn-primary, bg-primary, text-primary, etc..)...

/* import the necessary Bootstrap files */
@import "bootstrap/functions";
@import "bootstrap/variables";

$theme-colors: (
  primary: #333333;
);

/* finally, import Bootstrap */
@import '~bootstrap/scss/bootstrap.scss';

None of the solutions provided work. Some are close and will update the color use on most elements, but not all elements. I have tried them all (and every other alternative I can find on StackOverflow and other websites, but those solutions only affect the elements that are specifically referencing the color property and does not update those using the theme-color function to get the color.

The expected solution (and recommended by others) is

/* import only the necessary Bootstrap files */
@import "../../node_modules/bootstrap/scss/functions";
@import "../../node_modules/bootstrap/scss/variables";

/* -------begin customization-------- */
$colors: (
  "" + blue: #004C9E
);

/* 80 required to bring primary and secondary colors to AAA standards */
$theme-colors: (
  primary: #004C9E
);

// /* -------end customization-------- */

/* finally, import Bootstrap to set the changes! */
@import "../../node_modules/bootstrap/scss/bootstrap";

But this leaves 15 occurences of #007bff (the normal blue/primary color) throughout the generated custom.css. Examples of it occur in the pagination section, e.g.

.page-item.active .page-link {
  z-index: 1;
  color: #fff;
  background-color: #007bff;
  border-color: #007bff;
}

By setting both the $colors and the $theme-colors custom properties after the import of the functions.scss, and placing the statement to import the variables.scss AFTER these changes appears to set the new colors throughout. I presume that by setting these variables specifically, the bootstrap variables cannot override them.

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

/* -------begin customization-------- */
$colors: (
  "" + blue: #004C9E
);

/* 80 required to bring primary color to AAA standards */
$theme-colors: (
  primary: #004C9E
);

@import "../../node_modules/bootstrap/scss/variables";

/* put other customization in here */

// /* -------end customization-------- */

/* finally, import Bootstrap to set the changes! */
@import "../../node_modules/bootstrap/scss/bootstrap";

The may not seem right, but it does appear to work. I'm not a SASS expert, so maybe someone else could explain this better. I hope this helps anyone who may still be struggling to solve this issue.
