Colors

In Angular Material, colors play a significant role in defining the visual style and theming of your web application. Angular Material provides a predefined color palette system to help you maintain consistent and visually appealing color schemes throughout your application.

We've created a "@mixin" for managing colors, named "theme-var-colors" within the "_colors.scss" file located in the "mat-themes" folder. This mixin has been included in the "themes.scss" file.

_colors.scss

@mixin theme-var-colors($theme) {
    //code will come here
}

All the mixins need to be included in the "app-themes" section within the "themes.scss" file.

themes.scss

 @mixin app-themes($theme) {
     @include theme-var-colors($theme);
 }

Primary Color

The primary color is the main color used for the majority of your application's elements, such as headers, buttons, and backgrounds.

mat-primary (default): A predefined color palette that typically represents your application's primary brand color.
Custom colors: You can define your own custom primary color palette by specifying your preferred color in CSS or through Angular's theming system.

$primary: map.get($color-config, 'primary');
$color-primary: mat.get-color-from-palette($primary);
--color-primary: #{$color-primary};

The code snippet you provided can be explained as follows:

$primary: map.get($color-config, 'primary');

This line appears to be assigning a value to the variable $primary.
map.get() is likely a function used to retrieve a value from a map or dictionary.
It retrieves the value associated with the key 'primary' from a map named $color-config.
The value retrieved is assumed to be a color or a reference to a color.

$color-primary: mat.get-color-from-palette($primary);

This line assigns a value to the variable $color-primary.
mat.get-color-from-palette() is likely a custom or library function used to extract a color from a color palette.
It takes the previously assigned $primary value (presumably a color or color reference) and extracts the actual color value.

--color-primary: #{$color-primary};

This line sets a CSS custom property (also known as a CSS variable) named --color-primary.
The value of this custom property is assigned the value stored in the $color-primary variable.
The #{$color-primary} syntax is used to interpolate the value of $color-primary into the CSS custom property.
