Dark Red and Black Dye Module
The Dark Red and Black Dye Module can earned through the Reputation system, by reaching the Champion rank with Yavin. Once you have reached Champion, you can buy the schematic for this dye from the Yavin vendor for 100,000 Credits. The schematic, once learned, allows you to craft Dark Red and Black Dye Modules with Artifice level 500. If you have not reached Champion with Yavin, or do not have the Artifice crew skill, you can buy this dye from the GTN from other players.
When you use the Dark Red and Black Dye Module, it will dye the primary dye section of your armor Dark Red, and the secondary part of your armor Black.
All dye modules are one-use, so once you've added a Dark Red and Black Dye Module to your armor, you will not be able to remove it and reuse it later.
