Clean colour management with Sass

I thought I’d share a little setup I’ve been using for colour management in my projects and it’s all thanks to the new Sass Maps data type.

There have been a few tutorials discussing the use of maps. Jason Garber’s Sass Maps Are Awesome! is especially worth a read.

In my case I wanted to use Maps to reduce the number of long colour variable names I was using. e.g.

$site-footer-title-color: #FFF;
$site-footer-info-border-color: rgba(#FFF, 0.1);

Using Maps I’ve started to group colours based on element into a single variable:

$colors: (
nav: (
text: #333,
text-hover: #FFF,
bg: #FFF,
bg-hover: #FEF160
site-footer: (
title: #FFF,
info-border: rgba(#FFF, 0.1),
bg: #2A3137

The trouble with nesting maps like this is that to retrieve them we’d use:

.site-footer {
background-color: map-get(map-get($color, site-footer), bg);

This however is very ugly so I also have a helper function:

@function color($el, $color, $map: $colors) {
@return map-get(map-get($map, $el), $color);

This lets us do this:

.nav {

a {
background-color: color(nav, bg);
color: color(nav, text);

&:hover {
background-color: color(nav, bg-hover);
color: color(nav, text-hover);
.site-footer {
background-color: color(site-footer, bg);

Voila! A nice clean way of handling colours with Sass.
