*Cartel coins only but there is a permanent discount on all appearance designer kiosk options for subscribers up to 50% on a lot of options such as species change.
*If you want to change your character to a Cathar example, there is just a one time fee associated with all the Cathar options.
*Charging on a per slider basis if you just want to change your eye color for example, you can just jump in, change it right away and just get charged for that.
*For species changes, you can preview any species, play around with it, and then decide to unlock that species (if you dont already have it) directly from the kiosk for credits or cartel coins.
*Kiosks are placed in fleet and in capital worlds for now.

Dye Modules

Give you the ability to either dye entire armor sets or mix-match specific pieces of armor.
Two portions of your gear are dyeable: primary color and secondary color (i.e. for Havoc squad armor, white would be primary color and orange would be the secondary color).
Dye modules come in primary only, secondary only, and primary & secondary mixed.
Dye modules are consumables so you can insert them to change colors but gets destroyed once you pull them out.
You will see them in the cartel market for direct purchase, in future packs (i.e. contraband packs and beyond), a certain amount of colors are available through crafting (no details on the crew skills involved but you can RE them), and some unique colors from the security key and Collectors Edition vendors. Expect more colors to be added in the coming months.
Dye modules work off the current item enhancement/modding system. You will just open up the item modification panel for any gear you want to dye, drop a dye module in the new dye module slot, and hit accept to have it dyed.
Many pieces of equipment will be able to be dyed and you can preview a dye module on that specific piece of equipment before hitting accept.
Unified to chest also works you can just dye your chest piece and have the color applied to rest of your outfit.
Some items are not dyeable anything below L15, anything green (unless it comes from crafting), are generally not dyeable.
Lore outfits like armor of Jolee Bindo are not dyeable.
