An attempt to imitate a beautiful watercolour called ‘Lily in Shadow’ (1982) by Mark Adams, a San Francisco artist. I picked up an out of print book (1985) of his work while I was looking round a gallery in San Francisco a couple of years ago. His work (in a variety of media including watercolour, tapestry and stained glass) is astonishingly beautiful. In his paintings, he depicts everyday objects in colours full of light. You can see some of his watercolours at http://www.berggruen.com/#/artists/mark-adams/ He died in 2006.
