For the past 5 or so years, I’ve been using a small watercolor kit that fits <pretty well> in your pocket. It used to have a tiny brush that fit right inside, but that got left behind somewhere at Burning Man (oops – moop – sorry) and so now I carry a Chinese calligraphy brush with me. Not a big deal, it’s just that it doesn’t fit in the box. Anyway, I was looking at my colors, and just deleted the white (so useless), replacing it with a deep green from an old tube from 1995, then piled a bunch of turquoise in another pan – and then, wow! The colors are so intense! I’m going to have to replace most of my colors now that I know they were but pale representatives of the real thing. Here’s my sketch from the Hillside Club, where we saw Sheldon Brown (very technical, very good musicians!).
