Contrast and accessibility
On gray-800, white text has a contrast ratio of 14.67:1 and passes AAA at any text size; black text reaches 1.43:1.
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 gray-800 | 1.43:1 | Fail | Fail | Fail | Fail | 0.0 |
| White text on gray-800 | 14.67:1 | Pass | Pass | Pass | Pass | −104.3 |
| Gray-800 text on white | 14.67:1 | Pass | Pass | Pass | Pass | 101.5 |
| Gray-800 text on black | 1.43:1 | Fail | Fail | Fail | Fail | 0.0 |
Tints and shades
Each step mixes var(--color-gray-800) with white (tints) or black (shades) in gamma-encoded sRGB, the same result as color-mix(in srgb, var(--color-gray-800), white 25%) in CSS.

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, gray-800's complementary color is #322615 (close to darkslategray), its analogous colors are #152C35 and #272638, and its triadic partners are #372223 and #212C1C. For text on top, white gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #322615 |
| Analogous | −30°, +30° | #152c35#272638 |
| Triadic | +120°, +240° | #372223#212c1c |
| Split-complementary | +150°, +210° | #36231a#2a2a16 |
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 gray-800 is a cool color: its hue is 216° on the HSL wheel, in the green, blue and violet range that is conventionally called cool.
