What color formats does the converter support?

GoChronos Color Studio converts between HEX, RGB, RGBA, HSL, HSLA and OKLCH. All formats update simultaneously as you edit any value.

What is WCAG contrast ratio?

WCAG contrast ratio measures how readable text is against its background. WCAG 2.1 AA requires a minimum of 4.5:1 for normal text and 3:1 for large text; WCAG AAA requires 7:1.

What is OKLCH and why use it?

OKLCH is a perceptually uniform color space representing colors by Lightness, Chroma and Hue. Changes produce visually consistent steps, making it ideal for design systems and accessible color scales.

How do I check if two colors pass WCAG accessibility?

Enter your foreground (text) and background colors. The WCAG checker shows the contrast ratio and whether it passes AA and AAA standards for normal and large text.
