Tantan says the frame only comes in matte black. No custom paint options are available.
This tells me Tantan is probably just brokering the frames rather than manufacturing them. A little unsettling if you ask me.
When I originally saw the comments re: "Specialized offloading overstock" I first thought: "what a wacky conspiracy theory!". But now after digging into this thread, and playing a bit of "spot the difference" between photos of the original SL8 and the Seraph SL8...I'm becoming more convinced.
What a weird thing to do. They must be taking quite the loss on each frame sold this way if they really are overstock.
