Random, but I'm kind of annoyed they made it difficult to distinguish between Weiss' ice "arrows/bolts" and her Hard-Light lasers.

The ice is a somewhat darker shade of light blue and has a bit of a glittery effect, whereas the Hard-Light lasers are still cyan and move in curved paths.

So, based on the show, the ice arrows would be a light blue with a sparkle effect. By the way, Glitchee, I love the idea of ice Dust bracelets being used to form the arrows. It's such a cool image (no pun intended) and a good way to get around the issue of arrows being a hassle to carry around. Though, might I suggest also having another type Dust as a backup, in case your OC encounters a Grimm or a human or Faunus opponent that can use fire? Perhaps there's a way to use Hard-Light Dust as ammo.
