The black skin and red eyes is reaction between the geneseed and the inherent radioactivity on Nocturne, so if a successor chapter were raised on another planet, the issue wouldn't arise.
We also know that as the Heresy stands, there are only approx 800 Salamanders, so they would have been in no position to contribute to the second founding even if they wanted to. Which they weren't. Vulkan, along with Russ and Dorn, was a big opponent of the Codex Astartes, and eventually only went along with it in the end for fear of a second civil war if he didn't.
It is rumoured that the Black Dragons were founded using Salamander geneseed, but no-one knows for sure.
There may have been only 800 left at the end of the Heresy but at the end of Istvaan V there were approximately 3000 of them left as per the attached screenshot.
Good call about the Black Dragons, it would be interesting to know what they looked like out of their armour (ie their eyes and skin)

It is weird they have no successor chapters. Outside of their appearance giving people the willies, I wonder if Vulkan's status as a Perpetual has played any role in this? It probably wasn't known outside of highest levels of the Lords of Terra, but might go into the decision making to just leave them alone. Wouldn't that be interesting, to have a whole Chapter or even Legion of perpetuals?
I'm not sure that Vulkan being a perpetual would be know even by the High lords. I reckon that like Corax's ability it was probably known by the Emperor and probably Alpharius too as we know from the Seventh Serpent that he knows about Corax's ability.

Fair point but having extra resilient Marines descended from a loyal Legion wouldn't hurt.
