| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #ffc8ee |
| Analogous | −30°, +30° | #c6eeaf#91f4f2 |
| Triadic | +120°, +240° | #d9daff#ffd0b7 |

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.
