Ice Dust was first shown to be dark blue, in the scene where Ruby sneezes on red, dark blue, and yellow Dust, resulting in a fiery explosion with ice and electricity. Myrtenaster, Weiss' rapier, has


 * Red - Fire
 * Dark blue - Ice
 * Yellow - Lightning
 * White - Air (Now. Was most likely earth/rock in Volume 2)
 * Purple - Gravity (Most likely)
 * Cyan/Light blue - Likely responsible for the barriers she creates

Right now, I'm wondering if they actually changed the color of ice Dust from dark blue to light blue, just like how they changed air Dust from green to white. So, let's discuss the evidence.

Supporting Evidence
There was no dark blue Dust visible in the ice biome in the tournament. The crystal clusters in the ice biome were light blue. They're hard to notice since they look like ice, but they are of similar shape to the Dust crystals in the volcanic and geyser biomes. Plus, Ruby shot one of the crystals in order to freeze Nadir's legs.

Questionable/Opposing Evidence
Blake did not appear to be touching or holding an ice Dust crystal when she made an ice clone in Round One. This could suggest that there is ice Dust mixed in with the ice, though it's also possible that Blake had Dust vials loaded into Gambol Shroud.

However, there is also the fact that the burst effect that came from the Dust that Ruby shot behind Nadir had a somewhat dark blue color on the edges.

Supporting Evidence
Neon's nunchucks glow light blue when she is using ice Dust.

Questionable/Opposing Evidence
However, concept art shows her nunchucks glowing pink, despite there being no prior evidence of pink Dust existing. It is entirely possible that the pink mode is meant to be fire Dust, which is red.

Supporting Evidence
In Heroes and Monsters, Reese and Neon work together to freeze the legs of a Paladin. When this happens, the designs on Reese's hoverboard are actually light blue.

Questionable/Opposing Evidence
However, Reese's hoverboard isn't entirely consistent, even when we ignore the fact that it appears to still be using "green = air". In Round One, she loads a bright orange Dust crystal into it, but the designs turn red. They glow bright orange when she melts the ice to free Nadir, but the rest of the times she uses the Dust while attacking Blake, the designs remain red.

Myrtenaster
Recall the six Dust colors that I listed at the beginning of this post:


 * Red - Fire
 * Dark blue - Ice
 * Yellow - Lightning
 * White - Air (Now. Was most likely earth/rock in Volume 2)
 * Purple - Gravity (Most likely)
 * Cyan/Light blue - Likely responsible for the barriers she creates

In Weiss' Volume 5 Character Short, Myrtenaster still has those six colors, and she uses ice.

So, the questions are...

1. Did they switch ice and whatever makes barriers between the dark blue and light blue vials of Dust?

2. Did they change what color of Dust makes ice and forget to change that Dust slot in Myrtenaster to reflect that? There is the fact that Dew's spear has a green crystal and Reese's hoverboard has green designs, despite air Dust's color changing from green to white.

Or

3. Is ice Dust still dark blue, with the lighter blue stuff we saw in Volume 3 just being inconsistent designs? Or maybe the inconsistency is that both colors now make ice?
