Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, olive-900's complementary color is #1C1C22 (close to midnightblue), its analogous colors are #201C16 and #1A1E18, and its triadic partners are #161E21 and #211A1E. For text on top, white gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #1c1c22 |
| Analogous | −30°, +30° | #201c16#1a1e18 |
| Triadic | +120°, +240° | #161e21#211a1e |
| Split-complementary | +150°, +210° | #191d23#1f1b21 |
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-900 is close to neutral: its OKLCH chroma is only 0.013, so its temperature comes from context. The faint 60° hue gives it a slightly warm cast.
