Maul's skin is red; his tattoos are black. At least according to the old Tales story, Marked: [image=http://images2.wikia.nocookie.net/__cb20080103043848/starwars/images/3/3f/YoungDarthMaul.jpg] [image=http://images4.wikia.nocookie.net/__cb20080103044659/starwars/images/7/76/DarthMaulGettingHisTatoos.jpg] The recent TCW Super Night Bros. retcon might affect the canon status of some parts of that story, of course, but it's the best answer we have.
As far as TCW is concerned, I was under the impression that Sidious took him before he was tattooed, then applied his own Sith tattoos on him, which all the Sith in Legacy ripped off from...
I've always thought Zabrak tattoos were a terrible idea, because the idea of Sith Tattoos was so much cooler...
I agree completely... I mean Darth Maul should have been a one off with his tattoos, but the TCW shows he was just painted red... Every male Zabrak on Dathomir has them now...
Well, there was a retcon proposed that the Zabraks on Dathomir are leftovers from the ancient Sith academy there, which I think is super cool, except that every Zabrak everywhere has face tatoos....
I prefer this retcon. thus Zabrak tatoos originate with Sith tatoos and Maul got both. ironic that Jedi Master Zabrak have Sith Tatoos too then like Eeth Koth and Agen Kolar. maybe Zabrak introduced their tatoo cult to the Sith of the NSW and Iridonian academy spread the trend, even to Dathomir once Zabrak moved there to open another academy. thus we got it all in one. about Zabraks natural skincolor though... Eeth and Agen were a light brown/darker-white more akin to human skincolors while Dathomir and Maul Zabrak are either red/yellow/orange or black. I am not sure how much we can rely on that Tales story to keep Maul as naturally redskinned. it is more likely the Dathomir Zabrak are dark/blackskinned and vary in colors due to clanaffiliation and such rather than have them all the other way around red, yellow and orange and with black tatoos. (though no idea if that works tatoo-technique wise) Zabrak have been shown mostly with human skincolor variations so far, and the tatooed Zabrak nearly all had black as base color and other color variations for the tatoos. depends thus if we want to make Zabrak skincolors more diverse or if we diversify the tatoo colors and keep the skintone variations smaller.
For Legacy's sake, I think we should keep Zabrak skintones in the human wheelhouse and just assume that Sith tattoos tend to be black and red.
It's so much kinkier (and so much more in keeping with the idea of the dark side as a seducer) to think this is the answer. For that reason alone, I dislike Zabrak tattoos.
What I don't get is how Maul's tats even became an issue in the first place. Terrible writing, like it was done by someone who knew NOTHING about Darth Maul: Didn't know his home planet. Didn't know about his tats. Didn't know he was dead...
