In his book "Color and Meaning - Art, Science and
Symbolism", author John Gage speaks regarding the meaning attributed to
colours: "As it happens, the only 'school' of colour-analysis in the
history of art owes its development, not simply to the theoretical framework
proposed in the nineteenth century by the Swiss critic Heinrich Wolfflin, who
focused on the formal characteristics of visual style, including colour, but
also, and more importantly, to the stimulus of the more recent philosophical
tradition of phenomenology, represented in Germany chiefly by the philosopher
Edmund Husserl. Lorenz Dittman's wide-ranging study, 'Farbgestaltung und
Farbtheorie in der abendlandischen Malerei' ('Colour-structure and
Colour-theory in Western Painting', 1987), is only the most important summation
of a tradition of Koloritgeschichte (author's note: Colour history)."[7]
