Psychology

Dark cyans feel aquatic and technical — deep ocean, industrial machinery, precision instruments.

History

Cerulean, a blue-green pigment introduced in the nineteenth century, became important to Impressionist painters for capturing sky and water with unprecedented freshness.

Design use

Practically speaking, this deep cyan is most at home as a grounding element in print design — covers, footers, section dividers. On screen it suits dashboards and interfaces where a serious tone matters.

Colour pairings

When it comes to colour harmony, combine this cyan with coral and warm white for a fresh, modern palette, or with deep navy and charcoal for a more serious, technical feel.
