SCSS Color Variables
While SCSS adds many powerful features to standard CSS, variables can be one of the most useful for maintaining consistency in your web design. Defining color variables makes it simple to reuse colors as you prototype and develop your website, eliminating the need to memorize every single HEX code or HTML color name.
Setting up your SCSS color variables
If you are new to SCSS, variables are a core concept but are quite straightforward. In SCSS, variables are prefixed with a '$' sign and can be named anything you like. Here, we will define a few basic color variables to be used later in our stylesheets.
Remember, to leverage variables or any other SCSS features, your stylesheet must have the '.scss' file extension and a preprocessor must be integrated into your website's build process. You will need to ensure Sass is installed and configured in your development environment.
SCSS
$color-red: #FF0000;
$color-green: #00FF00;
$color-blue: #0000FF;Using SCSS variables in your stylesheets
Now that we have defined some color variables, it's time to apply them. You can use SCSS variables just as you would use regular values for any CSS property, just be sure to include the '$' prefix to indicate it's a variable.
This will produce CSS with whatever value you initially assigned to the variable. In our case, the output will look like this:
SCSS variables are extremely powerful, and they can be used for much more than just color. Try using them for font styles and families, different breakpoints, or transition timings. Go wild!

h1 { color: $color-red; }
p { color: $color-green; }
a { color: $color-blue; }CSS
h1 { color: #FF0000; }
