National Gallery 18 June – 7 September 2014 Physics, art and neurology all feature in this exhibition - the materials that create the pigments the artists use to create the works that create the effects in the brain of the viewer. Exhibits of painting, ceramics, minerals, and textiles. Dealing with lapis lazuli, cobalt, vermilion, cadmium, verdigris, viridian - which sound like characters from a fabulous fantasy. Gold and silver too. http://www.nationalgallery.org.uk/whats-on/exhibitions/colour-exhibition
