Tailwind cyan scale
Contrast and accessibility
On cyan-700, white text has a contrast ratio of 5.27:1 and passes AA for normal text; black text reaches 3.97:1.
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.

|---|---|---|---|---|---|---|
| Black text on cyan-700 | 3.97:1 | Fail | Pass | Fail | Fail | 28.4 |
| White text on cyan-700 | 5.27:1 | Pass | Pass | Fail | Pass | −81.0 |
| Cyan-700 text on white | 5.27:1 | Pass | Pass | Fail | Pass | 75.6 |
| Cyan-700 text on black | 3.97:1 | Fail | Pass | Fail | Fail | −26.1 |
Tints and shades
Each step mixes var(--color-cyan-700) with white (tints) or black (shades) in gamma-encoded sRGB, the same result as color-mix(in srgb, var(--color-cyan-700), white 25%) in CSS.

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, cyan-700's complementary color is #9A5334 (close to sienna), its analogous colors are #007B7A and #396BA4, and its triadic partners are #924F79 and #746B0D. For text on top, white gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #9a5334 |
| Analogous | −30°, +30° | #007b7a#396ba4 |
| Triadic | +120°, +240° | #924f79#746b0d |
| Split-complementary | +150°, +210° | #9c4d57#8d5e10 |
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 cyan-700 is a cool color: its hue is 193° on the HSL wheel, in the green, blue and violet range that is conventionally called cool.

- What is the hex code for Tailwind cyan-700?
- In Tailwind CSS v4, cyan-700 is oklch(52% 0.105 223.128), which converts to #007595 (rgb(0, 117, 149)) in sRGB after gamut mapping, because the OKLCH value is outside sRGB. In Tailwind v3 the same name was #0E7490.
- What is the difference between cyan-700 in Tailwind v3 and v4?
- v3 used the hex #0E7490; v4 redefined the palette in OKLCH as oklch(52% 0.105 223.128). In v3, cyan-700 was #0E7490. The v4 value is ΔE OK 1.1 away, below the point where most people can tell them apart; v4 is more saturated.
- How do I use cyan-700 in plain CSS?
- Tailwind v4 defines every palette color as a theme variable, so in CSS you write var(--color-cyan-700). By default Tailwind only emits the variables your project uses; @theme static emits all of them.
- Can you use white text on cyan-700?
- White text on cyan-700 has a contrast ratio of 5.27:1, which passes AA for normal text but not AAA under WCAG 2.2. Black text reaches 3.97:1 and passes AA only for large text (24 px, or 18.66 px bold, and up). In APCA terms that is Lc −81.0 for white and Lc 28.4 for black.
- Which CSS named color is closest to cyan-700?
- The closest is teal (#008080) at ΔE OK 5.5, followed by darkcyan and steelblue.
