A small color guide

Choose a duotone palette that fits the mood

A darker first color preserves depth. A brighter second color gives highlights energy. More distance between them creates crisp separation; a closer pair feels softer and more editorial.

Analogous

Neighboring hues feel calm, polished and cohesive.

Complementary

Opposing hues add energy and poster-like contrast.

Brand-led

Use a dark neutral plus your signature brand color.
