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.

🎭

Colour pairings

For palette building, this blue pairs naturally with warm neutrals — tawny beiges, soft terracottas, aged brass — which amplify its cool character by contrast. Analogous blue-violets and blue-greens give a more cohesive, tonal result.
