Contrast and accessibility
On darkseagreen, black text has a contrast ratio of 9.75:1 and passes AAA at any text size; white text reaches 2.15:1.
WCAG 2.2 contrast ratios (success criteria 1.4.3 and 1.4.6: AA needs 4.5:1 for normal text and 3:1 for large text, AAA needs 7:1 and 4.5:1). APCA Lc is the lightness contrast from the APCA-W3 0.0.98G model proposed for WCAG 3; a higher absolute value is more readable, and Lc 75 is its suggested minimum for body text.

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, darkseagreen's complementary color is #C89DCB (close to plum), its analogous colors are #ACB57A and #76BFAB, and its triadic partners are #95AEE2 and #DC9B95. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #c89dcb |
| Analogous | −30°, +30° | #acb57a#76bfab |
| Triadic | +120°, +240° | #95aee2#dc9b95 |
| Split-complementary | +150°, +210° | #b1a5dc#d799b1 |
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?
DarkSeaGreen is a cool color: its hue is 120° on the HSL wheel, in the green, blue and violet range that is conventionally called cool.
