Garth,
I had no idea that the variations were that many either. The Raw Umber I used was from a Danish firm called Artifix. It is also in the cool end of the scale and does not show the yellow that much. I think that it looks like your # 2 and it is also a heavy tinter. The Umber I have been using the most is from Daler-Rowney, it is more yellow, but I ran out of it.
Alex,
I also use the Raw Umber as a neutral and find it very useful. In the company of reds and bright ochers in the skintones it is a wonderful cool neutral, and I do not disagree with you in that or anything else for that matter. My prime interest, in here, besides of the excelent company, is to learn.
