title: How to use color string references in ASP.NET
body: <p>I find myself duplicating colors all over my Styles.css. When I would like to change that color, i would have to change it for about 10 times (and more as i go). 
  In Android you can write colors in an xml file and refer to them when you need a color. 
  Is there a way to do this in ASP.NET or css?
  I am sorry if there already is a solution somewhere on the internet, I am sure someone solved this, I just can not find it.</p>
