“50 Shades of Almost Everything”, by Mary M. Lane (The Wall Street Journal, June 14- 15, 2014), provides a tantalizing preview of the National Gallery (London) exhibit, “Making Colour” which will open on Wednesday, June 18th. What the many visitors who are sure to come to the museum will find are beautiful paintings and in depth information about the development, manufacture and use of pigments in the years 1300-1900. It makes one wish she was going to London this summer.
