Psychology

Mid blue dominates corporate and tech branding precisely because it reads as dependable without being cold.

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.
