In this template you will notice there aren’t any predefined stylesheets with different colors. The fact it’s just too complicated to maintain multiple stylesheets and the easiest and most recommended way of changing the main predominant color of the template is to simply:

1. Open template.css with your favorite editor
2. Hit Search & Replace (if you don’t know, try Ctrl+H or Ctrl+F)
3. In the search field add this hex color code which is used now #cd2122 and in the replace field add your own desired color code.
