Change the default Paint-It-Black/Simply-Red themes of any Last.fm page to whatever colors you want (plus minor fixes).

What is modified: the main header (with the Last.fm logo) and the color of some headings (user name/artist name, Recently Listened Tracks, Top Artists, Top Albums, Top Tracks, Shoutbox, Friends, Journals, Groups, Listening Now, Top Listeners etc).

You can select two colors below. The result of the default colors could be seen in the screenshot. Refresh this page if you want to change the colors again after installing this code. For a cool dark theme try for example Color1 = #333333 and Color2 = #555555.
