Contrast and accessibility
On sky-200, black text has a contrast ratio of 15.78:1 and passes AAA at any text size; white text reaches 1.33:1.
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 sky-200 | 15.78:1 | Pass | Pass | Pass | Pass | 87.4 |
| White text on sky-200 | 1.33:1 | Fail | Fail | Fail | Fail | −18.6 |
| Sky-200 text on white | 1.33:1 | Fail | Fail | Fail | Fail | 16.2 |

Tints and shades
Each step mixes var(--color-sky-200) with white (tints) or black (shades) in gamma-encoded sRGB, the same result as color-mix(in srgb, var(--color-sky-200), white 25%) in CSS.

Color harmonies
Rotating the hue in OKLCH while keeping lightness and chroma, sky-200's complementary color is #FFD4BC (close to peachpuff), its analogous colors are #B2EBEE and #C9E0FF, and its triadic partners are #FECFE3 and #DFE3B7. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #ffd4bc |
| Analogous | −30°, +30° | #b2ebee#c9e0ff |
| Triadic | +120°, +240° | #fecfe3#dfe3b7 |
| Split-complementary | +150°, +210° | #ffd0ce#f2dbb3 |
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 sky-200 is a cool color: its hue is 201° on the HSL wheel, in the green, blue and violet range that is conventionally called cool.
Nearest named and Tailwind colors
