Contrast and accessibility
On yellowgreen, black text has a contrast ratio of 11.15:1 and passes AAA at any text size; white text reaches 1.88:1.
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 |
|---|---|---|---|---|---|---|
| Black text on yellowgreen | 11.15:1 | Pass | Pass | Pass | Pass | 68.4 |
| White text on yellowgreen | 1.88:1 | Fail | Fail | Fail | Fail | −39.8 |

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, yellowgreen's complementary color is #D599FF (close to plum), its analogous colors are #DBB700 and #1ADB87, and its triadic partners are #67C0FF and #FF8BA8. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #d599ff |
| Analogous | −30°, +30° | #dbb700#1adb87 |
| Triadic | +120°, +240° | #67c0ff#ff8ba8 |
| Split-complementary | +150°, +210° | #a3b0ff#ff86e4 |
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?
YellowGreen sits on the boundary: its hue of 80° on the HSL wheel is a yellow-green, which reads warm next to blues and cool next to reds and oranges.
