John Dyer Painting. Summer Blue, TrescoBlue echiums, blue sea, blue sky and a blue boat all create a wonderful sense of cool calm seaside fun in 'Summer Blue, Tresco' by artist John Dyer. Puffins and seagulls fly across the sky and a Scotty dog plays with its owners on the glistening white sand of the Scilly Isles. A perfect piece of Tresco.
