I was a smoker for a few years. I quit 5 years, 2 months, and 3 days ago. It feels like much less time than that. Only occasionally in my smoking days were there bright colors surrounding me. I keep trying to restrain my palette and failing. I just want to use lots of colors, to make new colors and textures. I think I'm going to give up on restraint, and assume that this rainbow-palette leaning is just part of my style.
