A Sass color getter that also handles transparency

_get-color.scss

// Color names come from https://www.color-blindness.com/color-name-hue/
// The color values can be any valid color format: hex, rgb, hsl, CSS color names,
// etc. But probably best _not_ to use CSS color names.
$palette: (
	'black':           #000,
	'cornflower-blue': #55abf2,
	'grey':            #808080,
	'fire-engine-red': #d12118,
	'forest-green':    #20a037,
	'limeade':         #56b02c,
	'maya-blue':       #78bffa,
	'nero':            #171717,
	'pelorous':        #2a7dc2,
	'rio-grande':      #bfce18,
	'saffron':         #f0c63b,
	'silver-sand':     #bcbbb8,
	'smalt':           #004d8d,
	'white':           #fff,
	'wild-sand':       #efedea,
);

// Get the named color from our color map, with optional opacity.
// @param  string $color   A named color found in our $colors map.
// @param  number $opacity Desired opacity, defaulting to 1 (full opacity).
// @return color           The requested color with the alpha value. Remember that "color" is a value type of its own in Sass.
@function get-color( $color, $opacity: 1 ) {
	
	// Check to make sure the named color we requested exists in our $colors map.
	@if map-has-key( $palette, $color ) {

		// If so, return the color value along with the alpha channel value.
		@return transparentize( map-get( $palette, $color ), 1 - $opacity );
	}
	
	// If the requested color name was not found in our map, return magenta instead
	// (so it's obvious that something is wrong without completely erroring out).
	@return #f0f;
}

// Usage:
a {
	color: get-color( 'pelorous' );
}

.semi-transparent-background {
	background: get-color( 'forest-green', 0.5 );
}

So many fistbumps. This is great work!
