Contrast and accessibility
On green-400, black text has a contrast ratio of 11.80:1 and passes AAA at any text size; white text reaches 1.77:1.
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.
| Pair | Ratio | AA | AA large | AAA | AAA large | APCA Lc |

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, green-400's complementary color is #FF81F6 (close to violet), its analogous colors are #A7CE00 and #00DCC2, and its triadic partners are #9EB6FF and #FF957F. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #ff81f6 |
| Analogous | −30°, +30° | #a7ce00#00dcc2 |
| Triadic | +120°, +240° | #9eb6ff#ff957f |
| Split-complementary | +150°, +210° | #cda2ff#ff8db4 |
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 green-400 is a cool color: its hue is 150° on the HSL wheel, in the green, blue and violet range that is conventionally called cool.
