It's different.

Theory Time: Myrtenaster actually has diminute lines across it's surface, and the weapon just gets "filled" with the Dust when Weiss...does that. The lines have a just-as-small glass covering them to prevent the Dust from leaking out, but given they are transparent one can still see the Dust, which because of the lines's shape and size, look like the weapon is being covered in some slightly-glowing lines.

Non-Theory Time: The Dust in Cinder's clothes actually glow, a lot, while the lines in Myrtenaster, while they also glow, is in a noticeable, greatly smaller amount, and given they glow less, the color would appear less "light", which is why it still looks red in Myrtenaster, while it looks orange when Cinder uses it.

Besides, it's likely Cinder uses a lot more energy (which explains why her's glows more). She uses the Dust in all her dress, Myrtenaster only uses Dust in 1 small canister or whatever.

Also, I never said they used that with Dust so it fit Cinder. They're not changing it's color, they're making the specific Fire Dust Cinder uses in her dress, glow to a point it looks orange instead of pink, because it would remind people more of "Fire" than pink would.
