Oregon is much like Seattle weather-wise, but with a degree less rain. We still grow webs between our toes so we can paddle better. If anything the M Graham doesn’t dry out enough and keeps some of the ‘tacky’ texture you get right from the tube. As with all the brands, there are exceptions. Their Gamboge dries too hard, which is a pain because it is a beautiful color.
More and more, I’m drawn to single pigment colors. It’s just easier when you mix to avoid mud. Not that I avoid it. Sometimes, I think I’m possessed and have to have every color in a mix. My brush just keeps dipping itself into more and more colors!
