WCAG contrast, checked in one click.
Vivix is a native menu bar app that checks whether any two colors meet WCAG contrast requirements — pass/fail badges for every level, a screen eyedropper, and color blindness simulation, computed entirely on your Mac.
Every WCAG level, live
Normal text, large text, and UI component thresholds update instantly as you adjust either color — no separate check per level.
Screen eyedropper
Pick any on-screen color with Apple's native color sampler — sandboxed, no special permissions required.
Color blindness simulation
Simulate deuteranopia, protanopia, and tritanopia, each with its own contrast ratio — see your palette the way color-blind users do.
Private by design
Vivix makes no network calls. Every calculation runs locally, sandboxed, start to finish.
