Colour bibles! If you are as preoccupied by lovely colours (and lovely illustrations of lovely colours) as I am, these vintage books are a must . “The new science of colour” by Beatrice Irwin published in 1916. “Colour” by George Hirst published in 1900. “Solfege de la Couleur” by Edouard Feur in 1953 and the “ABC of Colour” in 1948.
