ColorTab containers include 6 different colors in two styles (with a wood tab on the left and without the wood tab).  All containers can include the standard min/max, print, rss feed, etc, buttons.  The title area can also be word-wrapped and the color tab will expand to fit.  Also, notice that all the container buttons visible to visitors have been colored to match the colors of the skin.

These can also be used as colored text boxes for a quick announcement by placing all the text in the title.
