I agree that it depends on the game.
A realistic game should have a Link with dirty blond hair, while bright yellow blond fits perfectly to a comic style Link.
I definitely don't want the pink hair back, that was okay in a game where the colours were a bit strange in general, but in a modern game I wouldn't like it.
But maybe that's just my opinion because that's how I'm used to it and a Link with dark hair would looked good, too...
