Plugin registeres simple widget within wordpress blog, that allows any visitor to change background 
color of theme. Actually it doesn’t change theme’s css file, but renders some style tag to user 
browser, that change the color locally. 
New background color associates only with user, that setted the color, and it tracks from cookie. 
So, if first visitor sets background color to ‘Rose’, second visitor can choose ‘Lime’ and third can 
leave that attribute to default and everyone get what they want at same time. 
If blog visitor sets background color to ‘Default’, browser explicitly deletes the cookie. Otherwise, 
cookie deletes itself after 30 days. 
Widget uses 4 ‘web-safe’ colors – #00FF00 (lime), #00FFFF (bluegreen), #9933FF (violet) and
FF0033(rose).
