(Update)
At least in .NET v1.1, the BackColor property works for each TabPage, but the color only takes effect for the common area below the tabs. On my TabControl, I don't have any common area, so I can't see it.
Looking for a way to set the BackColor of the *page* part of the TabPage, where the text is. This is probably the part that can't be done.

That's lame - apparently System.Windows.Forms.TabControl
does not support the BackColor property. Tried it on the control as a whole, then on each individual TabPage I was adding - no dice.
Google groups search confirms this.
Here's a 3rd party tab control that does support colored tab pages, among other controls.
