Kremer Pigmente
Kremer Pigmente is a shop in NYC that specializes in fine pigments and raw materials for painting. The place is a gold mine for both classic colors and zany brights. I picked up some cold-pressed linseed oil and dammar gum for varnish, as well as some fresh gold ochre and titanium white, but also invested in a turquoise that I thought would do well for a street sign in one of my paintings. Also got my first glass muller, which makes paint mixing a lot more efficient and breaks up the powder so it can dissolve into the oil more fully. Had to splurge on a fantastic set of retouching brushes as well. Painting heaven. Can't wait to go back.
George Kremer was also featured on one of my favorite Radiolab episodes, about color. That particular segment is about the color Gambodge, and it starts at 15:47 if you're curious: http://www.radiolab.org/story/211193-perfect-yellow/
