It would depend - sometimes it's just that I'm not a fan of particular colors and combinations, but others that are a fan of those colors would love it (I personally don't like purple or green, and not a big fan of blue either) However other times the shade I picked isn't really a good match, and it would look off no matter who is looking at it. And sometimes it's a fabric that is just too close to another in look, and it muddies the design.
So if it was just that it wasn't something I'm a big fan of, since it's a gift I'd probably leave it. If it was one of the other two, I'd probably change it.
