What WCAG levels does MiroMiro check?

MiroMiro checks both AA and AAA compliance levels for normal text (4.5:1 for AA, 7:1 for AAA) and large text (3:1 for AA, 4.5:1 for AAA), following WCAG 2.1 guidelines.

Can I check contrast directly on a live website?

Yes. With MiroMiro's Chrome extension, hover over any text element to instantly see its contrast ratio against its background — no manual color input needed.

What contrast ratio is considered accessible?

WCAG 2.1 requires a minimum ratio of 4.5:1 for normal text (AA level) and 3:1 for large text. AAA level requires 7:1 for normal text and 4.5:1 for large text.

Does it work with transparent backgrounds?

MiroMiro resolves the effective background color by traversing parent elements, accounting for transparency and layered backgrounds to give you accurate contrast ratios.

Is WCAG compliance legally required?

In many regions, yes. The ADA (US), EAA (EU), and other accessibility laws reference WCAG standards. Checking contrast is one of the simplest ways to improve accessibility compliance.
