Frequently Asked Questions

Does my colour value leave my browser?

No. The conversion runs entirely in JavaScript on this page.

Why does my picked colour change slightly?

Some colour spaces (LAB / OKLab / wide-gamut) can express colours that fall outside sRGB. Those values are clamped back into the displayable range.
