Changing Windows Vista/7's Transparency Color

Question

Ok, so I've heard that the color Microsoft decided to use for there Transparency is Black. Which would explain why black text is invisible when drawn/placed onto a Glass surface.

Wouldn't it just make sense for us to change the transparency color (black) BACK to Magenta? Why didn't they do this again? Is it even possible to change this color?

Answer 1

I'm not sure about chainging the transparent color, but you could render #010101 text and it should be dark enough for black, no? On a glass surface pure black could be hard to see anyway.
