Well, I don't know about which colo(u)r scheme is my favorite but there was one that Window$ 3.1(?) had which was quite obnoxious- the "Hot Dog" scheme. We had one guy at work who must have loved it because whenever he used the PC (we had shared ones back then) that scheme showed up!

I've noticed in later releases of Window$ that it disappeared...!

No wire bias here- I'm standing on neutral ground.
