Light Gray and Deep Red Dye Module
The Light Gray and Deep Red Dye Module can earned through the Reputation system, by reaching the Legend rank with Galactic Solutions Industry. Once you have reached Legend, you can buy the schematic for this dye from the Galactic Solutions Industry vendor for 100,000 Credits. The schematic, once learned, allows you to craft Light Gray and Deep Red Dye Modules with Artifice level 400. If you have not reached Legend with Galactic Solutions Industry, or do not have the Artifice crew skill, you can buy this dye from the GTN from other players.
When you use the Light Gray and Deep Red Dye Module, it will dye the primary dye section of your armor Light Gray, and the secondary part of your armor Deep Red.
All dye modules are one-use, so once you've added a Light Gray and Deep Red Dye Module to your armor, you will not be able to remove it and reuse it later.
