Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, olive-800's complementary color is #2A2932 (close to darkslategray), its analogous colors are #2F2922 and #272C25, and its triadic partners are #222C31 and #31272C. For text on top, white gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #2a2932 |
| Analogous | −30°, +30° | #2f2922#272c25 |
| Triadic | +120°, +240° | #222c31#31272c |
| Split-complementary | +150°, +210° | #252b32#2e2830 |
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 olive-800 is close to neutral: its OKLCH chroma is only 0.016, so its temperature comes from context. The faint 60° hue gives it a slightly warm cast.
