What is WCAG contrast compliance?

The Web Content Accessibility Guidelines (WCAG 2.1) require a contrast ratio of at least 4.5:1 for normal text (Level AA) and 7:1 (Level AAA) to ensure readability for people with visual impairments.

Can I copy individual color format strings?

Yes. Click the "Copy" button next to any format (HEX, RGB, HSL, HSV, CMYK) to instantly copy CSS-ready strings.

How are CMYK values calculated?

CMYK is a subtractive color model used in printing (Cyan, Magenta, Yellow, Key/Black). The tool uses standard RGB-to-CMYK conversion algorithms for quick print reference.
