Menu Bar Tint
Apple has introduced a proper way to turn off menu bar translucency from the "Desktop & Screensaver" system preference pane in Mac OS X 10.5.2, rendering Menu Bar Tint obsolete, in our humble opinion.
We'll leave this online for those who need to stay with earlier versions of Mac OS X 10.5 and those who simply like to tint their menu bars.
This little application is for those who, like us, don't want a translucent menu bar when working with Mac OS X 10.5 "Leopard" and have thus made it opaque by means of Steve Miner's environment variable trick. Once you've made your menu bar opaque this way, you'll notice that the menu bar has become very white, and that it looks very plain.
Running Menu Bar Tint in the background — as a log-in item, preferably — will make your newly opaque menu bar feel more at home among all the other user interface elements in Mac OS X. You can even have the menu bar's tint depend on whether your mouse hovers over it. And if you feel like going wild with colors, you're free to do so, too.
