I've looked at the forum posts a bit to find out about this, but so far no luck.
Does any paint company make the neutral grays for the munsell gray scale in oils? I do know that Golden makes them in acrylic, but I wanted to experiment with them and I don't paint in acrylic, just in oil and tempera.
I know that it is possible to make my own, but without the munsell printed color charts it's impossible to get the grays exact. And I'm just a bit too thrifty to put out the funds for the munsell books, at least at this point.
