## What is Vesper Colors?

Vesper Colors is a free WCAG 2.2 color contrast checker for designers, developers, and accessibility practitioners. Check any color pair instantly, build palettes, and explore full color profiles - all in one app.

Check
Enter any two colors and instantly see their contrast ratio with AA and AAA pass/fail results for both normal and large text. A live preview shows exactly how your text will look at real sizes. Tap any color to open the full-featured HSV color picker.

Preview
See your color pair applied across real UI components - navigation, hero section, reversed layout, form inputs, footer, data tables, and charts. Switch between normal and color blind simulation modes to check accessibility across vision types.

Palette
Build multi-color palettes with full-screen color bars. Add, edit, reorder, and delete colors. Tap any bar for quick actions: copy hex, check WCAG contrast, view shades, or jump to the full color profile. Share your palette with a single tap.

Profile
Explore any color in depth. See HEX, RGB, HSL, and CMYK values with one-tap copy. Check contrast against white and black. Simulate how the color appears to users with Protanopia, Deuteranopia, Tritanopia, and Achromatopsia. Browse shades, tints, tones, hues, temperatures, and four color harmonies - all tappable to explore further.

Vesper Colors is completely free with no subscription, no sign-up, and no ads. Part of the Vesper accessibility suite alongside Vesper Inspect and Vesper Audit.
