Psychology

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

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
