Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, mist-100's complementary color is #F4F2F2 (close to whitesmoke), its analogous colors are #F1F3F2 and #F1F3F4, and its triadic partners are #F3F2F4 and #F3F3F1. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #f4f2f2 |
| Analogous | −30°, +30° | #f1f3f2#f1f3f4 |
| Triadic | +120°, +240° | #f3f2f4#f3f3f1 |
| Split-complementary | +150°, +210° | #f4f2f3#f4f2f2 |
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-100 is close to neutral: its OKLCH chroma is only 0.002, so its temperature comes from context. It has no perceptible hue.
