I keep my palette clean maybe the first hour of a painting. After that it's just layers of dried paint I mix into, scrape off, add more on top. Someone told me last week I should clean it between sessions and I looked at them like they'd suggested I set my hair on fire.

I know painters who treat their palette like an altar. Wipe it down, lay fresh piles, everything in its place. I've tried. I last about twenty minutes before I start working wet into wet and the whole thing turns into a crusty ruin again. There's something about the chaos that helps me find colour faster, I think. I don't have to decide, I just pull from whatever's there and adjust.

Today I've got a smear of burnt sienna that's been there since Tuesday, a pool of medium I accidentally spilled, and what might be ultramarine or might be cobalt, I can't tell anymore because it's mixed with the grey from yesterday's shadows. It's fine. The painting is coming along.

Maybe I'll scrape it clean when this one's done. Maybe not.
