Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, mist-600's complementary color is #5E524F (close to darkslategray), its analogous colors are #4B5956 and #4D575E, and its triadic partners are #5B5259 and #58554B. For text on top, white gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #5e524f |
| Analogous | −30°, +30° | #4b5956#4d575e |
| Triadic | +120°, +240° | #5b5259#58554b |
| Split-complementary | +150°, +210° | #5e5254#5c534c |
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-600 is close to neutral: its OKLCH chroma is only 0.017, so its temperature comes from context. The faint 191° hue gives it a slightly cool cast.
