Tailwind orange-700: #CA3500
In Tailwind CSS v4, orange-700 is defined as --color-orange-700: oklch(55.3% 0.195 38.402), which is #CA3500 in hex and rgb(202, 53, 0): a medium-dark, vivid brown. In Tailwind v3, orange-700 was #C2410C.
In OKLCH, orange-700 has a lightness of 55.3%, chroma 0.195 and hue 38.4°.
This OKLCH value lies outside sRGB. The hex #CA3500 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 0.7298 0.2573 0.0511).
In v3, orange-700 was #C2410C. The v4 value is ΔE OK 2.1 away; v4 is more saturated.

Contrast and accessibility
On orange-700, white text has a contrast ratio of 5.22:1 and passes AA for normal text; black text reaches 4.02:1.
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.

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, orange-700's complementary color is #0082A1 (close to steelblue), its analogous colors are #C8295B and #A65F00, and its triadic partners are #008C4E and #5E5DE0. For text on top, white gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #0082a1 |
| Analogous | −30°, +30° | #c8295b#a65f00 |
| Triadic | +120°, +240° | #008c4e#5e5de0 |
| Split-complementary | +150°, +210° | #00877f#0074d7 |
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 orange-700 is a warm color: its hue is 16° 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 orange-700?
- In Tailwind CSS v4, orange-700 is oklch(55.3% 0.195 38.402), which converts to #CA3500 (rgb(202, 53, 0)) in sRGB after gamut mapping, because the OKLCH value is outside sRGB. In Tailwind v3 the same name was #C2410C.
- What is the difference between orange-700 in Tailwind v3 and v4?
- v3 used the hex #C2410C; v4 redefined the palette in OKLCH as oklch(55.3% 0.195 38.402). In v3, orange-700 was #C2410C. The v4 value is ΔE OK 2.1 away; v4 is more saturated.
- How do I use orange-700 in plain CSS?
- Tailwind v4 defines every palette color as a theme variable, so in CSS you write var(--color-orange-700). By default Tailwind only emits the variables your project uses; @theme static emits all of them.
- Can you use white text on orange-700?
- White text on orange-700 has a contrast ratio of 5.22:1, which passes AA for normal text but not AAA under WCAG 2.2. Black text reaches 4.02:1 and passes AA only for large text (24 px, or 18.66 px bold, and up). In APCA terms that is Lc −79.8 for white and Lc 29.7 for black.
- Which CSS named color is closest to orange-700?
- The closest is firebrick (#B22222) at ΔE OK 6.9, followed by crimson and sienna.
