CircleCI Primary on this page is the real value, not a screenshot: exact hex, RGB, HSL and OKLCH, ten tints and ten shades, classic harmonies, and WCAG contrast with fixes — plus the 3 public brands that use it and the palettes it appears in.

Colors that go with CircleCI Primary

Blue, Taupe and Dark Orchid lead the list. Each partner is a real named colour with the reason it works — a wheel relationship, a neutral that carries it, or a pairing lifted from a palette or brand system that actually shipped — and every pair opens in the palette tool.
