}

Accessible esempi to try

Start from a real palette or a safe high-contrast pairing, then adjust it for your project.

What the score means

The higher the ratio, the easier the combination is to read for more people and more display conditions.

AA normal text

Usa at least 4.5:1 for body copy, navigation, links, buttons and most interface text.

AA large text

Large text can pass at 3:1, but higher contrast usually still feels clearer and more professional.

AAA text

7:1 is the stronger target for long reading, critical information, accessibility-first products and dashboards.
