Crook Farm, Lune estuary. Oil on card, 6"x8"

I often walk down here from home and it's a lovely spot to paint. The light on this afternoon was clear which isn't usually the case. As autumn progresses I'll paint this again and try to contrast the conditions. I use a very limited palette and it was interesting trying to get the subtle turquoise of the sky from ultramarine which is essentially a 'warm' blue. I found that if I added blue to a viridian and white mix I could get quite a nice turquoise, adding more blue as I moved higher.
