Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, mist-500's complementary color is #80706D (close to dimgray), its analogous colors are #677976 and #6A7680, and its triadic partners are #7C707A and #787467. For text on top, white gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #80706d |
| Analogous | −30°, +30° | #677976#6a7680 |
| Triadic | +120°, +240° | #7c707a#787467 |
| Split-complementary | +150°, +210° | #807073#7e7268 |
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 mist-500 is close to neutral: its OKLCH chroma is only 0.021, so its temperature comes from context. The faint 191° hue gives it a slightly cool cast.
