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, olive-400's complementary color is #A8A8B7 (close to darkgray), its analogous colors are #B2A89C and #A4ADA0, and its triadic partners are #9DADB4 and #B5A5AC. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #a8a8b7 |
| Analogous | −30°, +30° | #b2a89c#a4ada0 |
| Triadic | +120°, +240° | #9dadb4#b5a5ac |
| Split-complementary | +150°, +210° | #a2abb7#afa6b3 |
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-400 is close to neutral: its OKLCH chroma is only 0.021, so its temperature comes from context. The faint 60° hue gives it a slightly warm cast.
