I just went to the book store and I was looking at Sargent books. I found one painting I really liked the technique. It's called "Ricordi di capri" and it's in the book "Great expectations: John singer sargent paints children". Anyway, it's a picture of a big white wall in capri and 2 small kids on the stairs. The whole wall though has a very very rough look, and I wondered how he paints like that and what technique to use to emulate it. I've tried, but I just end up with a kind of muddy blended blob that looks more like i messed up than a really good "rough" look with tons of broken color. Here is another example, however this isn't nearly as good as the one in the book. I realize a lot of this is probably just a thinned wash with a rough brush, but that's not what i'm talking about. its done with thick paint (i think). It's almost as if he used thick paint and made it very rough, then let it dry, then did a glaze overtop with a darker color so there are lots of "pinpoints" of dark and white. Hopefully you understand
My other question is, wahts the best way to make a neutral gray. Also, a good black, I haven't really found the right colors yet. I use the schmid palette.
