Black and Pale Yellow Dye Module
The Black and Pale Yellow Dye Module can be crafted by players who have the Artifice crew skill levelled to crafting level 470. Once you have reached Artifice level 470, the schematic for this dye can be purchased directly from the artifice crew skills trainer. This dye can also be bought from other players on the GTN, or crafted and then sold on the GTN.
When you use the Black and Pale Yellow Dye Module, it will dye the primary dye section of your armor Black, and the secondary part of your armor Pale Yellow.
All dye modules are one-use, so once you've added a Black and Pale Yellow Dye Module to your armor, you will not be able to remove it and reuse it later.
