Look, man, I don't get it either.
But would you rather have a great-playing game with the colors slightly off, or a color-perfect game that plays like MLB 2K9?
I'm not about to throw away a fun game because of a tiny thing like colors.
Now, if you said wild pitches/passed balls, that I'd get, because that's a genuine issue that affects gameplay. Those are lessened now, but still not to acceptable levels. They ARE working on it, that much we do know.
