Orange and red color palettes

Orange and red are neighbors on the color wheel (about 29° apart), an analogous pairing. Analogous schemes feel harmonious and natural because the hues share undertones; the trade-off is low hue contrast, so separate them by lightness when they sit next to each other.

In practice, orange brings warmth and energy, and works hardest as an accent, while red brings urgency and is best kept to calls to action and highlights. The palettes below combine both families, strongest matches first; open any of them to see its contrast matrix and copy the hex codes, CSS variables or Tailwind config.

Hue contrast is not text contrast: two colors can look completely different and still fail WCAG as text and background. Every palette page shows which pairs pass, and the contrast checker suggests the nearest passing shade.
