Collection of artworks in shades of blue by Robert Hope, Federico Madrazo, Raimundo de Madrazo y Garreta, Ferdinand Max Bredt, Edvard Munch, Rik Wouter, Arkady Rylov, Jules-Élie Delaunay, Kees van Dongen, Odilon Redon and other painters. The assigning of symbolic meanings to colors is probably as old as symbolism itself. “In fact, words are well adapted for description and the arousing of emotion, but for many kinds of precise thought other symbols are much better”. (John B. S. Haldane)
