[Gimp-user] Text that changes colour depending on background colour?

[steveyraff <forums gimpusers com>]

Hey guys. 

I am designing a product. 

The product is a small aluminium box, painted white. On this box, there is a
black graphic of a bat. Scrawled across this graphic, will be the product name.

To see the product name - the text needs to be coloured BLACK on the parts where
it is over the white background, but it needs to be coloured WHITE on the parts
where it is over the black graphic.

I hope this makes sense?

I have no idea how to do this sort of intelligent coloration, so some help is
much welcomed.

Many thanks, 
Steve.
