What Plunging Cave Inside Dismaying

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

In practical terms, a deep cyan 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, 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.
