Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, orangered's complementary color is #00A6C7 (close to lightseagreen), its analogous colors are #FB3A7E and #D67800, and its triadic partners are #00B25C and #737FFF. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #00a6c7 |
| Analogous | −30°, +30° | #fb3a7e#d67800 |
| Triadic | +120°, +240° | #00b25c#737fff |
| Split-complementary | +150°, +210° | #00ac9e#0098ff |
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?
OrangeRed is a warm color: its hue is 16° on the HSL wheel, in the red, orange and yellow range (0° to about 70°, plus reds above 330°) that is conventionally called warm.
