This looks like a good use case for `$cmPurple`, a variable for the purple color used throughout the site, thanks to the `@import "colors"`, which references this [colors](https://github.com/CodeMontageHQ/codemontage/blob/master/app/assets/stylesheets/colors.css.scss) file. (This and the larger style guide notions aren't well-documented yet, but hopefully will be in the future!)
