30 named colors · 168 combinations
Deep crimsons, scarlets, and vermillions from Sanzo Wada's 1933 dictionary. Red in the Japanese shikisai tradition carries imperial authority and ceremonial weight — kurenai (crimson) was reserved for court robes; shu (vermillion) marks every shrine gate.
Named colors
From a standard colour wheel, Red anchors these four classic schemes. Each swatch is computed from its exact hue, so every hex is a real, usable pairing.
the hue directly opposite — the highest-contrast pairing, good for a single bold accent.
the two neighbours on the wheel — a calm, cohesive scheme that feels effortless.
two hues an even third of the wheel away — balanced and lively without clashing.
the two colours either side of the complement — the contrast of a complement, softened.
Red is a deep, muted tone (HSL 0°, 57%, 38%), which makes it a versatile mid-tone for accents, buttons or blocks. For text it passes WCAG AA for body text against a light background (7.7:1) — safe for paragraphs, buttons and labels. When you do set type on it, use light lettering. Pair it with its complement (#2A9A9A) for a focal accent, or with its analogous neighbours (#9A2A62 and #9A622A) for a quieter, harmonious feel.
