I\'ll second the recommendation for the flesh colours. I\'d recommend Tanned, Tanned Shadow, Rosy, Rosy Shadow, Golden Skin and Golden Shadow in particular. You can use Linen White to mix highlights with those or mixes for paler skintones so don\'t need to get the paler ones straight off.
I like almost all the RMS browns, and most of the yellows. I particularly recommend Oiled Leather, Shield Brown and Walnut Brown as very flexible paints I used for all kinds of things. Ditto the Bone Triad which is a grayed bone and useful for bones, rocks, teeth, old wood and more. I haven\'t seen equivalents to those colours in too many paint palettes, so they\'re useful to try on that level, too.
I have had some chalking problems with two sets of paints - the Olive Greens and the Autumn Browns. I\'m not even sure it\'s all the paints in those triads, I think it\'s just Olive Shadow, Olive and Harvest Brown, but I haven\'t tested enough to be sure. Palomino Gold isn\'t quite as smooth as most of the paints, but not truly problematic like the Olives and Autumns.
Getting one of the kits with the new paints is a good idea to test out whether they\'ll work with your style and preferences as long as you don\'t mind not getting the dropper bottles.
