Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, mauve-950's complementary color is #080B08 (close to black), its analogous colors are #0A090D and #0D090A, and its triadic partners are #0C0A07 and #070B0C. For text on top, white gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #080b08 |
| Analogous | −30°, +30° | #0a090d#0d090a |
| Triadic | +120°, +240° | #0c0a07#070b0c |
| Split-complementary | +150°, +210° | #0a0b07#070b0a |
Computed in OKLCH: the hue is rotated by 180° (complementary), ±30° (analogous), ±120° (triadic) and 180° ±30° (split-complementary) while lightness and chroma stay fixed. Results that fall outside sRGB are brought back with the CSS Color 4 gamut mapping algorithm. Because this uses OKLCH, the values differ from tools that rotate hue in HSL, but every color keeps the same perceived lightness.
Warm or cool?
Tailwind mauve-950 is close to neutral: its OKLCH chroma is only 0.008, so its temperature comes from context. The faint 300° hue gives it a slightly cool cast.
