Tailwind CSS v4 default palette
Tailwind yellow-600: #D08700
In Tailwind CSS v4, yellow-600 is defined as --color-yellow-600: oklch(68.1% 0.162 75.834), which is #D08700 in hex and rgb(208, 135, 0): a medium, vivid orange. In Tailwind v3, yellow-600 was #CA8A04.
In OKLCH, yellow-600 has a lightness of 68.1%, chroma 0.162 and hue 75.8°.
This OKLCH value lies outside sRGB. The hex #D08700 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 0.7763 0.5425 0.0417).
In v3, yellow-600 was #CA8A04. The v4 value is ΔE OK 2.0 away, below the point where most people can tell them apart; v4 is more saturated.
Tailwind yellow has very high lightness through 400, so only the 700 and darker shades are suitable for text on white.

Contrast and accessibility
On yellow-600, black text has a contrast ratio of 7.14:1 and passes AAA at any text size; white text reaches 2.93:1.
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 yellow-600 | 7.14:1 | Pass | Pass | Pass | Pass | 48.6 |
| White text on yellow-600 | 2.93:1 | Fail | Fail | Fail | Fail | −60.8 |
| Yellow-600 text on white | 2.93:1 | Fail | Fail | Fail | Fail | 55.5 |
| Yellow-600 text on black | 7.14:1 | Pass | Pass | Pass | Pass | −46.3 |
Tints and shades
Each step mixes var(--color-yellow-600) with white (tints) or black (shades) in gamma-encoded sRGB, the same result as color-mix(in srgb, var(--color-yellow-600), white 25%) in CSS.

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, yellow-600's complementary color is #4E99FA (close to cornflowerblue), its analogous colors are #E77335 and #A79D00, and its triadic partners are #00B1B3 and #BF76DB. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #4e99fa |
| Analogous | −30°, +30° | #e77335#a79d00 |
| Triadic | +120°, +240° | #00b1b3#bf76db |
| Split-complementary | +150°, +210° | #00aadf#9286f7 |
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 yellow-600 is a warm color: its hue is 39° on the HSL wheel, in the red, orange and yellow range (0° to about 70°, plus reds above 330°) that is conventionally called warm.

- What is the hex code for Tailwind yellow-600?
- In Tailwind CSS v4, yellow-600 is oklch(68.1% 0.162 75.834), which converts to #D08700 (rgb(208, 135, 0)) in sRGB after gamut mapping, because the OKLCH value is outside sRGB. In Tailwind v3 the same name was #CA8A04.
- What is the difference between yellow-600 in Tailwind v3 and v4?
- v3 used the hex #CA8A04; v4 redefined the palette in OKLCH as oklch(68.1% 0.162 75.834). In v3, yellow-600 was #CA8A04. The v4 value is ΔE OK 2.0 away, below the point where most people can tell them apart; v4 is more saturated.
- How do I use yellow-600 in plain CSS?
- Tailwind v4 defines every palette color as a theme variable, so in CSS you write var(--color-yellow-600). By default Tailwind only emits the variables your project uses; @theme static emits all of them.
- Can you use white text on yellow-600?
- White text on yellow-600 has a contrast ratio of 2.93:1, which fails AA even for large text under WCAG 2.2. Black text reaches 7.14:1 and passes both AA and AAA. In APCA terms that is Lc −60.8 for white and Lc 48.6 for black.
- Which CSS named color is closest to yellow-600?
- The closest is darkgoldenrod (#B8860B) at ΔE OK 4.4, followed by peru and goldenrod.
