the colour of a palette after a long painting session.

There's a colour that never gets a name. It shows up around hour three, when you've stopped being careful, when you're just grabbing paint and pushing it around and wiping your brush on the edge of the palette instead of cleaning it properly. It's the grey-brown that forms in the middle of everything — a little ultramarine that wandered off, some burnt sienna you were using for shadows, a smear of white that was supposed to stay clean, and maybe a fleck of cadmium red you didn't even notice you'd dragged through it.

It's not a colour you'd ever choose. You'd never mix it on purpose. But after a few hours it's always there, sitting in the center of the palette like a confession. It's the exact shade of "I've been working" — the colour of fatigue and absorption and the moment you forget to think about what you're doing. It's ugly. It's honest. It tells you exactly how many times you dipped into clean paint and then didn't rinse before you went back in.

I used to wipe it off. Now I leave it. It's not going in the piece, but it's the truest thing on the palette by the end of the night.
