The tool supports two-way real-time conversion between the most popular color formats including **HEX, RGB, HSL, HWB, LCH, CMYK**, and can also provide the closest English Color Name.
Does this color converter work offline?
Yes. Once the page is loaded, all calculations and color conversions happen 100% locally in your browser without requiring a network connection.
How do I use these color codes in CSS?
You can copy the result directly (e.g., `rgb(79, 70, 229)`) and paste it directly into your CSS files. The tool formats the output to be directly compatible with modern CSS.
What are LCH and HWB used for?
These are modern color spaces supported in modern CSS. LCH is based on human perception (Lightness, Chroma, Hue), making it excellent for creating smooth, perceptually uniform gradients compared to standard RGB or HSL.
