The question is why? Everything seems to be like ingame except color crystals. Colors are different even with bloom disabled. Preview screen color has more blue I would say.

As seen on the screen bellow, color crystals in preview screen are not exactly matching their color ingame. They seem to have overall darker colors, not just the edges. http://img849.imageshack.us/img849/7006/6qvg.jpg It's not a big deal, but it's quiet annoying to be left to your own imagination when it comes to buying a color crystal.
