Add better support for Sass

[Jesper Haug Karsrud]

I've been meaning to add better support for Sass by reusing more of the CSS color scheme. Making an issue here now so that I won't forget.

Would love to see Sass variables have a color associated with them. Also, keeping the CSS and Sass schemes in check (green color values #000000);

@colbyfayock Would you like to see green color values in CSS, or white color values in Sass? :)

[Colby Fayock]

@jkarsrud Personally liked the white, but not opposed to the green! :P Will just get used to the green if matched in .css.

@colbyfayock Hehe. If you want, you can submit a pull request for both the variable and color value coloring :)
