Psychology

Dark blues project authority, depth and reliability — the colour of deep water, the night sky, and tailored suits.

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.
