"You're insane," my wife said. "You can't paint fireworks in pitch darkness."
"It's not pitch dark," I said. "Every once in a while there's a flash. Plus there's some light from that tiki torch."
I was mad obsessed. I hunched over the sketchbook in my lap. I couldn't make out any chroma or hue, and only could distinguish three values at best: white, middle tone, and black.
From time to time someone from the party came over and stood next to me, munching on potato chips. "What are you doing?"
"I'm painting," I replied. I glanced up at their puzzled faces, lit by flashes of red light and sulphur smoke.
Here's what I was using:
White, black, golden ochre, and Venetian red casein
Round 6 watercolor brush
Flat 1/4 inch synthetic brush
