Dwarf Barak Varr players, what are the proper colors?

I see painting tutorials showing all green. I see armies painted in all turquoise. Based on this website, the shields are shown as being painted in Turquoise/Sea Foam and Cream versus any kind of green (https://cragfistsbrewery.weebly.com/dwarf-hold-colours.html).

But based on art from the Total War video games, Barak-Varr seems to be all dark green.

Which of these colors are correct?
