Psychology

In its darkest registers blue becomes serious and introspective: trustworthy, professional, slightly austere.

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

As a dark tone, it naturally lends itself to 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
