Contrast and accessibility
On orange-600, black text has a contrast ratio of 5.83:1 and passes AA for normal text; white text reaches 3.59:1.
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-600's complementary color is #009FC9 (close to cadetblue), its analogous colors are #F53A6C and #C87900, and its triadic partners are #00AC6B and #7D73FF. For text on top, black gives the higher contrast.
| Harmony | Rotation | Color |
|---|---|---|
| Complementary | +180° | #009fc9 |
| Analogous | −30°, +30° | #f53a6c#c87900 |
| Triadic | +120°, +240° | #00ac6b#7d73ff |
| Split-complementary | +150°, +210° | #00a6a1#008eff |
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-600 is a warm color: its hue is 18° on the HSL wheel, in the red, orange and yellow range (0° to about 70°, plus reds above 330°) that is conventionally called warm.
