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

In design terms, a mid-toned blue like this handles brand accents, data visualisation series, and illustrative elements. Its middle lightness gives it presence on both white and dark backgrounds.
