Title: Use variables and functions to make things clearer

I find it easier to tell when colors of different styles are the same when variables are used. Additionally, there are some instances where hand-creating a color (such as the current line highlight) gets in the way of future enhancements. This change introduces variables for all the appropriate color settings and uses functions such as lighten() and contrast() to make keeping the stylesheet up-to-date simpler.
