Black and Deep Blue Dye Module
The Black and Deep Blue Dye Module can earned through the Reputation system, by reaching the Champion rank with CZ-198. Once you have reached Champion, you can buy the schematic for this dye from the CZ-198 vendor for 100,000 Credits. The schematic, once learned, allows you to craft Black and Deep Blue Dye Modules with Artifice level 450. If you have not reached Champion with CZ-198, or do not have the Artifice crew skill, you can buy this dye from the GTN from other players.
When you use the Black and Deep Blue Dye Module, it will dye the primary dye section of your armor Black, and the secondary part of your armor Deep Blue.
All dye modules are one-use, so once you've added a Black and Deep Blue Dye Module to your armor, you will not be able to remove it and reuse it later.
