Maybe she has Ice Dust in one and Steam Dust in the other.

Edit: Personally, I would prefer it if she didn't have Ice Dust. IIRC only her main sword did...and it was a light blue crystal. If both did have one though, the typical guesses for what Dust types she has would be Steam & Ice (like you said), but maybe Wind as well. The wind certainly didn't act normal, and might've been the reason for all those snow lines too, though that might've just been the look for the situation. To me, I would've liked it better if the storm was accompanied by a large summoning glyph...that way most of the unobservant people could understand it was a group of summons and not some weird Ice Grimm, and plus it wouldn't look like they were made from nothing. Dark Blue was first shown to be ice, and depending on whether or not we can go by the color of Dust that CRWBY put right in front of us, it looks like Dark Blue might still be ice in the Weiss Character Short.

Wind is white. We got a dramatic closeup on the white Dust in Myrtenaster right before Weiss made a whirlwind in Never Miss a Beat, and Amber used a white Dust crystal to make gusts of wind.

I'd say the pale blue in Winter's sword is steam, since she hid in a cloud of steam while fighting Qrow, and there were pale blue Dust crystals in the geyser biome in the tournament.
