Tailwind CSS v4 default palette
Tailwind yellow-300: #FFDF20
In Tailwind CSS v4, yellow-300 is defined as --color-yellow-300: oklch(90.5% 0.182 98.111), which is #FFDF20 in hex and rgb(255, 223, 32): a very light, vivid amber. In Tailwind v3, yellow-300 was #FDE047.
In OKLCH, yellow-300 has a lightness of 90.5%, chroma 0.182 and hue 98.1°.
This OKLCH value lies outside sRGB. The hex #FFDF20 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 0.9827 0.8809 0.321).
In v3, yellow-300 was #FDE047. The v4 value is ΔE OK 1.6 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-300, black text has a contrast ratio of 15.82:1 and passes AAA at any text size; white text reaches 1.32:1.
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-300 | 15.82:1 | Pass | Pass | Pass | Pass | 87.7 |
| White text on yellow-300 | 1.32:1 | Fail | Fail | Fail | Fail | −18.3 |
| Yellow-300 text on white | 1.32:1 | Fail | Fail | Fail | Fail | 15.9 |
| Yellow-300 text on black | 15.82:1 | Pass | Pass | Pass | Pass | −87.8 |
Tints and shades
Each step mixes var(--color-yellow-300) with white (tints) or black (shades) in gamma-encoded sRGB, the same result as color-mix(in srgb, var(--color-yellow-300), white 25%) in CSS.

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, yellow-300's complementary color is #D5DCFF (close to lavender), its analogous colors are #FFD496 and #BCF667, and its triadic partners are #8BF1FF and #FFC6F7. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #d5dcff |
| Analogous | −30°, +30° | #ffd496#bcf667 |
| Triadic | +120°, +240° | #8bf1ff#ffc6f7 |
| Split-complementary | +150°, +210° | #bbe5ff#f0d1ff |
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-300 is a warm color: its hue is 51° on the HSL wheel, in the red, orange and yellow range (0° to about 70°, plus reds above 330°) that is conventionally called warm.
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 yellow-300?
- In Tailwind CSS v4, yellow-300 is oklch(90.5% 0.182 98.111), which converts to #FFDF20 (rgb(255, 223, 32)) in sRGB after gamut mapping, because the OKLCH value is outside sRGB. In Tailwind v3 the same name was #FDE047.
- What is the difference between yellow-300 in Tailwind v3 and v4?
- v3 used the hex #FDE047; v4 redefined the palette in OKLCH as oklch(90.5% 0.182 98.111). In v3, yellow-300 was #FDE047. The v4 value is ΔE OK 1.6 away, below the point where most people can tell them apart; v4 is more saturated.
- How do I use yellow-300 in plain CSS?
- Tailwind v4 defines every palette color as a theme variable, so in CSS you write var(--color-yellow-300). By default Tailwind only emits the variables your project uses; @theme static emits all of them.
- Can you use white text on yellow-300?
- White text on yellow-300 has a contrast ratio of 1.32:1, which fails AA even for large text under WCAG 2.2. Black text reaches 15.82:1 and passes both AA and AAA. In APCA terms that is Lc −18.3 for white and Lc 87.7 for black.
- Which CSS named color is closest to yellow-300?
- The closest is gold (#FFD700) at ΔE OK 2.0, followed by khaki and yellow.
