Why would I need LAB or OKLAB instead of HEX?

HEX is useful for implementation, but LAB and OKLAB are better when you care about perceptual changes in lightness and palette behavior.

Is this useful for frontend work?

Yes. The tool is especially useful when translating between design output and CSS-friendly formats like HEX, RGB, and HSL.

No. The conversion happens locally in your browser and no color data is sent to a server.
