18 of the best monochrome websites

Black and white is technically monochrome, but the term more broadly refers to any single-hue palette — a site using only shades of blue, green, or terracotta is also monochrome. The key is that all colour variation comes from adjusting lightness and saturation of one base hue.

A single-hue palette guarantees colour harmony and simplifies design decisions. It creates a strong, memorable brand association with that colour and forces designers to build hierarchy through other means — scale, weight, spacing, and tonal contrast.
