'Farm at Watendlath' is an old favourite , it really does capture the Lake District , the lines of the walls and the monumental nature of the fells. It's basically a palette of greens and greys but with strong contrasts of dark and light. The figures add a sense of mystery.
Whistlers ' Nocturne Blue and Silver Chelsea' was an interesting challenge in trying to analyse the colours in such a subtle piece ( and also a lesson in accuracy or not in reproduction) The top image is from the Tate website, the photo below what I took with my phone which show how much more varied and subtle the colours and tones were. It demonstrates how important it is to see artworks in the flesh. The bushstrokes were very evident - it looks like glazes over a darker ground and the boat looked like paint had been removed . Lovely murkiness ! It reminded me how much I enjoyed the exhibition 'Turner, Whistler,Monet' and had me returning to the catalogue!
