Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, darkturquoise's complementary color is #FD9097 (close to lightcoral), its analogous colors are #4ECFA2 and #3EC5F5, and its triadic partners are #D69AED and #E4A948. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #fd9097 |
| Analogous | −30°, +30° | #4ecfa2#3ec5f5 |
| Triadic | +120°, +240° | #d69aed#e4a948 |
| Split-complementary | +150°, +210° | #f191c6#f99969 |
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?
DarkTurquoise is a cool color: its hue is 181° on the HSL wheel, in the green, blue and violet range that is conventionally called cool.
