Today I tried the last four colors: cobalt violet, cobalt green, dark yellow and cadmium vermilion. The manufacturer still has some details to work on but I do want to see this brand in the stores because it's good for the market. It would probably face a tough struggle for survival though. What do we miss on the market as it is? Impeccable quality? Affordable prices? A variety of hues? Everything is already there when it comes to paints but if you find a way to make synthetic brushes as good at keeping the water as sable ones, I'll be more than happy to help you get rich. Or if you find a way to make organic Arches paper and sell it cheaper than ordinary Arches made of heavily pesticide-sprayed cotton!
