Tailwind CSS v4 default palette
Tailwind green-500: #00C950
In Tailwind CSS v4, green-500 is defined as --color-green-500: oklch(72.3% 0.219 149.579), which is #00C950 in hex and rgb(0, 201, 80): a light, vivid green. In Tailwind v3, green-500 was #22C55E.
In OKLCH, green-500 has a lightness of 72.3%, chroma 0.219 and hue 149.6°. It is the most saturated shade of the green scale.
This OKLCH value lies outside sRGB. The hex #00C950 is the sRGB fallback from the CSS Color 4 gamut mapping algorithm; on Display P3 screens browsers show a more saturated color, close to color(display-p3 0.3087 0.7748 0.3743).
In v3, green-500 was #22C55E. The v4 value is ΔE OK 2.7 away; v4 is more saturated.
Tailwind green is the standard success color; in v4 its mid shades moved to a more saturated OKLCH green than the v3 hex values.

Contrast and accessibility
On green-500, black text has a contrast ratio of 9.47:1 and passes AAA at any text size; white text reaches 2.21:1.
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 green-500 | 9.47:1 | Pass | Pass | Pass | Pass | 61.1 |
| White text on green-500 | 2.21:1 | Fail | Fail | Fail | Fail | −47.6 |
| Green-500 text on white | 2.21:1 | Fail | Fail | Fail | Fail | 42.9 |
| Green-500 text on black | 9.47:1 | Pass | Pass | Pass | Pass | −59.3 |
Tints and shades
Each step mixes var(--color-green-500) with white (tints) or black (shades) in gamma-encoded sRGB, the same result as color-mix(in srgb, var(--color-green-500), white 25%) in CSS.

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, green-500's complementary color is #ED68E6 (close to orchid), its analogous colors are #98B500 and #00C3A8, and its triadic partners are #7D9DFF and #FF6A57. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #ed68e6 |
| Analogous | −30°, +30° | #98b500#00c3a8 |
| Triadic | +120°, +240° | #7d9dff#ff6a57 |
| Split-complementary | +150°, +210° | #b983ff#ff5ca1 |
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-500 is a cool color: its hue is 144° on the HSL wheel, in the green, blue and violet range that is conventionally called cool.

- What is the hex code for Tailwind green-500?
- In Tailwind CSS v4, green-500 is oklch(72.3% 0.219 149.579), which converts to #00C950 (rgb(0, 201, 80)) in sRGB after gamut mapping, because the OKLCH value is outside sRGB. In Tailwind v3 the same name was #22C55E.
- What is the difference between green-500 in Tailwind v3 and v4?
- v3 used the hex #22C55E; v4 redefined the palette in OKLCH as oklch(72.3% 0.219 149.579). In v3, green-500 was #22C55E. The v4 value is ΔE OK 2.7 away; v4 is more saturated.
- How do I use green-500 in plain CSS?
- Tailwind v4 defines every palette color as a theme variable, so in CSS you write var(--color-green-500). By default Tailwind only emits the variables your project uses; @theme static emits all of them.
- Can you use white text on green-500?
- White text on green-500 has a contrast ratio of 2.21:1, which fails AA even for large text under WCAG 2.2. Black text reaches 9.47:1 and passes both AA and AAA. In APCA terms that is Lc −47.6 for white and Lc 61.1 for black.
- Which CSS named color is closest to green-500?
- The closest is limegreen (#32CD32) at ΔE OK 3.4, followed by mediumseagreen and yellowgreen.
