Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, zinc-700's complementary color is #404038 (close to darkslategray), its analogous colors are #3B4047 and #423E44, and its triadic partners are #463E3A and #3A423E. For text on top, white gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #404038 |
| Analogous | −30°, +30° | #3b4047#423e44 |
| Triadic | +120°, +240° | #463e3a#3a423e |
| Split-complementary | +150°, +210° | #443f38#3d413b |
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 zinc-700 is close to neutral: its OKLCH chroma is only 0.013, so its temperature comes from context. The faint 240° hue gives it a slightly cool cast.
