latex mix colors with colorlet and xcolor

To mix colors you need to have the xcolor package loaded first via:

\usepackage{xcolor}

And then you can mix two colors with

\colorlet{DarkBlue}{blue!80!black}

which means you mix 80% blue with 20% black. If you do not have a second color you mix the first with: "white".
