Tailwind CSS v4 default palette
Tailwind green-50: #F0FDF4
In Tailwind CSS v4, green-50 is defined as --color-green-50: oklch(98.2% 0.018 155.826), which is #F0FDF4 in hex and rgb(240, 253, 244): an off-white with a green tint. In Tailwind v3, green-50 was #F0FDF4.
In OKLCH, green-50 has a lightness of 98.2%, chroma 0.018 and hue 155.8°.
The value fits inside sRGB, so the hex #F0FDF4 represents it without loss on any screen.
In v3, green-50 was #F0FDF4. The v4 value is ΔE OK 0.0 away, below the point where most people can tell them apart.
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-50, black text has a contrast ratio of 20.06:1 and passes AAA at any text size; white text reaches 1.04:1.
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-50 | 20.06:1 | Pass | Pass | Pass | Pass | 102.8 |
| White text on green-50 | 1.04:1 | Fail | Fail | Fail | Fail | 0.0 |
| Green-50 text on white | 1.04:1 | Fail | Fail | Fail | Fail | 0.0 |
| Green-50 text on black | 20.06:1 | Pass | Pass | Pass | Pass | −104.4 |
Tints and shades
Each step mixes var(--color-green-50) with white (tints) or black (shades) in gamma-encoded sRGB, the same result as color-mix(in srgb, var(--color-green-50), white 25%) in CSS.

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, green-50's complementary color is #FFF5FE (close to ghostwhite), its analogous colors are #F6FCEF and #ECFDFB, and its triadic partners are #F5F8FF and #FFF5F1. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #fff5fe |
| Analogous | −30°, +30° | #f6fcef#ecfdfb |
| Triadic | +120°, +240° | #f5f8ff#fff5f1 |
| Split-complementary | +150°, +210° | #fcf6ff#fff4f7 |
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-50 is close to neutral: its OKLCH chroma is only 0.018, so its temperature comes from context. The faint 138° hue gives it a slightly cool cast.
Nearest named and Tailwind colors
Distance is ΔE OK, the Euclidean distance in OKLab multiplied by 100. Values under about 2 are hard to tell apart side by side.

- What is the hex code for Tailwind green-50?
- In Tailwind CSS v4, green-50 is oklch(98.2% 0.018 155.826), which converts to #F0FDF4 (rgb(240, 253, 244)) in sRGB. In Tailwind v3 the same name was #F0FDF4.
- What is the difference between green-50 in Tailwind v3 and v4?
- v3 used the hex #F0FDF4; v4 redefined the palette in OKLCH as oklch(98.2% 0.018 155.826). In v3, green-50 was #F0FDF4. The v4 value is ΔE OK 0.0 away, below the point where most people can tell them apart.
- How do I use green-50 in plain CSS?
- Tailwind v4 defines every palette color as a theme variable, so in CSS you write var(--color-green-50). By default Tailwind only emits the variables your project uses; @theme static emits all of them.
- Can you use white text on green-50?
- White text on green-50 has a contrast ratio of 1.04:1, which fails AA even for large text under WCAG 2.2. Black text reaches 20.06:1 and passes both AA and AAA. In APCA terms that is Lc 0.0 for white and Lc 102.8 for black.
- Which CSS named color is closest to green-50?
- The closest is honeydew (#F0FFF0) at ΔE OK 0.9, followed by mintcream and azure.
