Psychology

In its darkest registers blue becomes serious and introspective: trustworthy, professional, slightly austere.

History

Blue has been among the most valued pigments throughout history — ultramarine, ground from lapis lazuli, was once worth more than gold and reserved for the robes of the Virgin Mary in medieval painting.
