I go the real easy route. I use a pale flesh base which isn't
GW, but Kislev Flesh would work. Either as is, or lightened depending on the tone you want assuming you're painting them caucasian. My base is very very pale as I wanted a fair skinned Scandinavian look.
Anyways, getting on with it....
Prime white
Kislev Flesh
Then 1-2 coats of Ogryn Flesh wash.
Not the best picture maybe. I can take another if you want.
That's it. Sometimes I go around the edges of the armor and hairline with Agrax Earthshade if it's looking too red in those areas from the Ogryn Flesh. Quick and easy, which is great for
IG. Not as fancy as all the multiple step methods, but I think it looks great. One could go back in and do the highlights on top with lightened Kislev if desired I suppose. I haven't found it necessary.
