The Copper Border down Changing

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

In practical terms, a medium-dark blue like this works well as a primary background in dark themes, a strong border or divider, or a headline colour against a light surface. Combine with lighter tints of the same hue for a cohesive palette.

Colour pairings

In terms of colour combinations, complement this blue with amber and warm orange for high-contrast energy, or stay within blue-green and violet neighbours for a serene, cohesive feel.
