FAQ
What color formats do you support?
Our tools support HEX (3, 6, and 8-digit), RGB, RGBA, HSL, HSLA, and CSS named colors. The converter tool lets you switch between all of these formats instantly and copy the result with one click.
How does the contrast checker work?
The contrast checker calculates the luminance ratio between foreground and background colors per WCAG 2.1 guidelines. It tells you whether your color combination passes AA or AAA standards for both normal and large text sizes.
