Psychology

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

🏛️

History

The ancient Egyptians were among the first to produce blue pigment artificially — Egyptian blue, made from copper and sand, coloured the walls of pharaonic tombs.

✏️

Design use

Practically speaking, this deep blue is most at home as a background for light-coloured text, as a deep accent stripe, or as an anchoring tone in dark-mode interfaces. It pairs naturally with off-whites, warm creams, and metallic highlights.

Colour pairings
