These bookmarklets let you play with colors on any web page that does not make heavy use of images. They require Mozilla 1.5a+ because they use CSS3 HSL (Hue-Saturation-Lightness) colors.
(To keep bookmarklets in order to use them on other web pages, drag them to your Bookmarks Toolbar. Or, install them all at once.)
