Raven's blades changed colours because she literally changed blades - in fact, her old ones broke during the fight with Cinder, suggesting that Dust Blades are somewhat brittle and prone to breaking. Hence she has a whole cylinder of Dust blades on her hip with various colours.

She didn't apply Dust to the blade after the forging, she has a case full of blades made with Dust already imbued in the weapon. She plugs her handle in, spins the dial and connects a blade of the Dust type she wants, and then draws it. It's why her fighting style is based on Iado - the 'draw' style, because it's based around sheathing and redrawing her blade, which means she can replace blades as they break.

An exerpt from her weapon page:

When Raven connects the hilt with the scabbard, she can switch to a different Dust blade, or if the hilt does not have a blade, she can replace the blade. The Dust blades can also be broken after they have sustained too much damage, prompting her to switch to a new Dust blade during combat.
