A little more information might be helpful: what version of Vegas? nature of the source material? what video card?
I’ve been using Sony Vegas for nearly 15 years and have never had your problem, so my suspicion is that it’s coming from your computer rather than from the software, although that’s just a guess. Version 13 is the most recent. Search the Sony Vegas editor’s forum
to see if anyone else has reported a similar problem.
Perhaps more to the point, though, is how to fix the problem. I would suggest setting the correct levels first, then using color curves to tweak the color back into line. Be sure to use scopes when doing this.
