What we have here is a list of all of the currently available colors in the game, with information on how to get them (if we've found that yet). This information was gathered from both SWTOR official forums and Reddit, from a variety of different contributors.
This list is a work in progress and will be updated as more information is found.

BlueThis crystal pattern is learnt from an artiface trainer. High quality versions of this crystal are discovered through reverse engineering.
CyanREPUBLIC ONLY!!! Obtained from Columi gear, listed as "Light Blue" [LTBLUE]. Champion versions can be Cyan, but not removable.
GreenThis crystal pattern is learnt from an artiface trainer. High quality versions of this crystal are discovered through reverse engineering.
MagentaThis is one of the rarest items in the game. It is not acquired through reverse engineering. Also listed as "Light Red" [LTRED], Magenta has a few steps to do before you can get this one. Gargath, on Hoth drops a +33 Power schematic. Belsavis's Worldboss's, The Primal Destroyer, drops a +33 Endurance, a +33 Crit schematic and a +33 Power schematic.. The following are the steps for the main ingredient. Thanks to Taskcommnda

Second Step - Travel to the top of the really tall mountain on Hoth (X-907,Y 637) - The closest speeder is at the Leth Outpost and the mountain is clearly visible from here. Your buff will disappear and you will get the "Pure Shockfrozen Water" item placed into your inventory.
Third Step - Take a couple of level 50 friends and go to the Depleted White Adegan Crystal node on Ilum; to the west (-553,-5) and click it. A Force Ghost will spawn from the frozen pool (boss level 50 mob). A crystal will then spawn for the group a few yards away from the depleted crystal. Loot this for the Magenta Crystal.
note: the moisture vaporator's are around outpost Rennar in the Jundland area of tatooine
CONFIRMED: drops from a nearby crystal formation that appears after you defeat the force ghost, seems only 1 crystal per formation, though no one else in the group had the frozen water to summon the ghost we could only try it once.
OrangeHigh level Artifice (lvl 400), also drops from Corusant Worldboss, Nar Shadda Worldboss and Ulgo Siegebreaker on Alderaan [Note - "Normal" gems can be found in vendor sabers/gear as well]
PurpleEMPIRE ONLY!!! Tier 2 Empire Columi Gear, obtained via Hardmode Eternity Vault [Unconfirmed]. They can also be obtained from PvP sabers, but YOU CANNOT remove the crystal.
RedThis crystal pattern is learnt from an artiface trainer. High quality versions of this crystal are discovered through reverse engineering.
WhiteThe white crystal "found" by CatchDeathwalker was confirmed by Bioware to be a fraud. It is not available inagme at the moment.
YellowThis crystal pattern is learnt from an artiface trainer. High quality versions of this crystal are discovered through reverse engineering.
Let me know if you have any more information about how to get color crystals. I am going to update my '
New Players Guide to SWTOR' eBook soon and might include a complete list if I can put one together.
