Focus Ring Color Generator
Used by developers, writers, and creators worldwide.
A focus ring color generator produces a visible, accessible focus indicator color tuned to the surface it sits on. Give it your surface color and a hue, and it tests focus-ring shades at that hue until it finds one that meets the WCAG non-text contrast requirement of 3:1 against the surface, automatically going lighter on dark backgrounds and darker on light ones. It reports the chosen ring color along with the exact contrast ratio so you can confirm keyboard focus will actually be seen. Visible focus is a frequently failed accessibility requirement, and removing the default outline without a clear replacement locks out keyboard users; this gives you a compliant, on-hue alternative. Developers and designers use it to style :focus-visible outlines, define focus tokens, and pass accessibility audits. The result is a paste-ready hex code with the math to prove the indicator is genuinely visible.

FAQ
why does a focus ring need 3:1 contrast
Focus indicators are non-text UI components, and WCAG requires non-text elements to reach 3:1 contrast against adjacent colors. Below that, a keyboard user may not be able to see which control is focused.
why does the ring change on dark backgrounds
On a dark surface a dark ring would disappear, so the generator searches lighter shades of your hue, and on light surfaces it searches darker shades, always favouring the version that clears the contrast threshold.
should i ever remove the focus outline
Not without a replacement. Removing the default outline with no visible substitute fails accessibility. Use this on-hue ring with :focus-visible so the indicator appears for keyboard users without distracting mouse users.
