As someone who RP'ed twi'leks a lot on Star Wars Galaxies, I made a skin colour database for reference in our guild back there. This was based on several fanon sites, including the Temple of Kika'lekki (FYI, that site's been offline for a couple of years now). Using the data found on these sites, I made a colour wheel. The main 5 colours would be yellow (tolian), blue (rutian), brown (dorian), green (tukian) and purple (tyrian). The more exotic colours were white (torran), black (kerran), and finally red (lethan). You can find a copy of the wiki we had for it below, as well as a link to the colour wheel (since I haven't found out how to add images to this forum ) I want to stress that this is purely fanon, but it worked out fine for RP on SWG. Twi'leks can be found in all colours, some more common than others. Since the twi'leks had not always been so intertwined as they were during the time of the Galactic Civil War, different clans originally existed of monochrome members. As most twi'leks were highly religious, these monochrome clans all worshipped their deities in different ways. Rutian twi'leks Blue skinned, these twi'leks are also known as water twi'leks. They descended from an underground clan that practiced worship through the observation, use, and appreciation of water and its various forms. Pigment colour: Teal to dark blue. Aayla Secura, Xiaan Amersu, Nilim Bril, Orn Free Taa, Ann and Tann Gella, Numa, and Alema Rar, Mission Vao were rutian twi'leks. Dorian twi'leks Brown skinned, these twi'leks are also known as stone twi'leks. They descended from an aboveworld clan that practiced worship through the creation of great stone monuments. Pigment colour: Brown. Rianna Saren was a dorian twi'lek. Tukian twi'leks Green skinned, these twi'leks are also known as spirit twi'leks. They descended from an aboveworld clan that practiced worship through spiritual devotion, prayers, and the conducting of ceremonies, usually involving plants and fungi. Pigment colour: Light green to dark green. Oola, Dia Passik, and Laranth Tarak were tukian twi'leks. Tyrian twi'leks Purple skinned, these twi'leks are also known as music twi'leks. They descended from a clan that lived in aboveworld caves, much like a mix of both worlds, and practiced worship through music, dance, song, and poetry. Pigment colour: Dark purple to light purple and bright pink. Yuthura Ban, Kopecz, and Lunae Minx were tyrian twi'leks. Tolian twi'leks Yellow or orange skinned, these twi'leks are also known as fire twi'leks. They descended from an underground clan that practiced worship through the mastery and use of fire. Pigment colour: Orange to yellow. Tott Doneeta, Cham Syndulla, and Ayy Vida were tolian twi'leks. Torran twi'leks White skinned, these twi'leks were something of a rarity. They lacked a gene to give their skin any kind of pigmentation. Usually they had red eyes. Pigment colour: White to grey and pale pink. Lyn Me, Boc Aseca, and Bib Fortuna were torran twi'leks. Kerran twi'leks Black skinned, these twi'leks were even rarer than Torrans. A gene defect gave them a very dark colouring. Their eyes were usually very dark as well. Pigment colour: Dark grey to black. Lethan twi'leks Red skinned, these twi'leks were the rarest among their species. They can show up in any of the five clans and it is unknown what causes the red pigmentation. Efforts have been made to determine its cause, but it is believed to be a genetic anomaly. Most lethans spend their entire lives in fear and in hiding due to slave owners being willing to risk anything to own one. Pigment colour: Red. Shakka, Darth Ruyn, Darth Talon, and B'ink Utrila were lethan twi'leks. http://img14.imageshack.us/img14/1835/lekcolourwheelsmall.jpg
