I found 2 variants for the evo Vader on legacy collection, these come with black RA-7 leg. One f this Vaders was very burnt on his face, like Ep III Vader, the other has more shade than the original Vader with the astromech parts, This Vader was a bit tan, but could pass as pale.
I think the first Vader in legacy BD 8, depicted pale is the most accurated of them.
