Painting light on a moving sea and land is something I'm obsessed with. This small painting took longer than you'd expect. When you really look at a sunset, a whole palette of colours emerges that you don't anticipate: golds, bronzes, pinks, deep blues, all shifting minute by minute.

And those colours don't just live in the sky. They reflect down onto the shore, pulling the whole scene together. I used a lot of gold and bronze pigment in this piece to capture that warmth.

It's a small painting, but the light in it is big.
