Psychology

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

History

In Japanese aesthetics, blue — particularly indigo — has been a central colour for centuries: the slow-dyed textiles of Tokushima remain prized for their depth and permanence.

Design use
