Sass maps for color families

Written by

First time using Sass maps. Trying to easily create lots of css classes for a particular color.

	// ----
	// Sass (v3.4.14)
	// Compass (v1.0.3)
	// ----

	// Stacked Viz
	$viz-stacked-colors: ("orange": #F8D592 #F9A153 #FD7835 #C14040 #91233D, "red": #FEC9AD #FFA48B #EA7171 #B03C64 #7E095B, "green": #B1ECA7 #6CDF97 #37BE95 #137B7E #294469, "blue": #98DFE9 #51BBDF #3685D3 #4F50A6 #4E2969, "purple": #F9B2D2 #E188C3 #A853A8 #74459A #34307B);

	@mixin viz-stacked-colors {
	@each $name, $colorList in $viz-stacked-colors {
	@for $i from 1 through 5 {
	.viz-stacked-#{$name}-#{$i} {
	background-color: nth($colorList, $i);
	}
	}
	}
	}

	@include viz-stacked-colors;
