DANIEL SMITH Extra Fine Watercolors - classic watercolors of unsurpassed purity and permanence. The vision in the formulation of DANIEL SMITH watercolors was twofold; First and foremost, to produce watercolors that are the best in lightfastness and permanence.
Daniel Smith sold out to a conglomerate about 10 years ago. The reason you see so many urban sketchers using and promoting DS watercolor is because they get all they want for free. It is not bad paint, but there are filling problems such that tubes often have a lot of air in them. Separation issues as well. Pigmentation is good, but M Graham is better and does not have the problems that DS has. I was very disappointed.
