Tailwind CSS v4 default palette
Tailwind green-600: #00A63E
In Tailwind CSS v4, green-600 is defined as --color-green-600: oklch(62.7% 0.194 149.214), which is #00A63E in hex and rgb(0, 166, 62): a medium, vivid green. In Tailwind v3, green-600 was #16A34A.
In OKLCH, green-600 has a lightness of 62.7%, chroma 0.194 and hue 149.2°.
This OKLCH value lies outside sRGB. The hex #00A63E 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 0.2439 0.6408 0.2948).
In v3, green-600 was #16A34A. The v4 value is ΔE OK 2.4 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-600, black text has a contrast ratio of 6.52:1 and passes AA for normal text; white text reaches 3.21:1.
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-600 | 6.52:1 | Pass | Pass | Fail | Pass | 45.4 |
| White text on green-600 | 3.21:1 | Fail | Pass | Fail | Fail | −64.1 |
| Green-600 text on white | 3.21:1 | Fail | Pass | Fail | Fail | 58.7 |
| Green-600 text on black | 6.52:1 | Pass | Pass | Fail | Pass | −43.1 |
Tints and shades
Each step mixes var(--color-green-600) with white (tints) or black (shades) in gamma-encoded sRGB, the same result as color-mix(in srgb, var(--color-green-600), white 25%) in CSS.

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, green-600's complementary color is #C553C0 (close to mediumorchid), its analogous colors are #7E9500 and #00A28A, and its triadic partners are #5A7BFC and #E64B3C. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #c553c0 |
| Analogous | −30°, +30° | #7e9500#00a28a |
| Triadic | +120°, +240° | #5a7bfc#e64b3c |
| Split-complementary | +150°, +210° | #9b65eb#de4785 |
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-600 is a cool color: its hue is 142° on the HSL wheel, in the green, blue and violet range that is conventionally called cool.

- What is the hex code for Tailwind green-600?
- In Tailwind CSS v4, green-600 is oklch(62.7% 0.194 149.214), which converts to #00A63E (rgb(0, 166, 62)) in sRGB after gamut mapping, because the OKLCH value is outside sRGB. In Tailwind v3 the same name was #16A34A.
- What is the difference between green-600 in Tailwind v3 and v4?
- v3 used the hex #16A34A; v4 redefined the palette in OKLCH as oklch(62.7% 0.194 149.214). In v3, green-600 was #16A34A. The v4 value is ΔE OK 2.4 away; v4 is more saturated.
- How do I use green-600 in plain CSS?
- Tailwind v4 defines every palette color as a theme variable, so in CSS you write var(--color-green-600). By default Tailwind only emits the variables your project uses; @theme static emits all of them.
- Can you use white text on green-600?
- White text on green-600 has a contrast ratio of 3.21:1, which passes AA only for large text (24 px, or 18.66 px bold, and up) under WCAG 2.2. Black text reaches 6.52:1 and passes AA for normal text but not AAA. In APCA terms that is Lc −64.1 for white and Lc 45.4 for black.
- Which CSS named color is closest to green-600?
- The closest is forestgreen (#228B22) at ΔE OK 7.6, followed by mediumseagreen and olivedrab.
