GLSL vec3 to hex
This assumes the vector holds encoded values. If it came out of lighting math it is linear, and you need the linear reading to get the right hex.
Paste a GLSL vec3 value. Other formats work too.

How the conversion works
This assumes the vector holds encoded values. If it came out of lighting math it is linear, and you need the linear reading to get the right hex.
Both formats are computed from a single canonical representation (CIE XYZ with a D65 white point, held in floating point) rather than by chaining one format into the next. That matters because chained conversions accumulate rounding error, and because it means a color that cannot be represented in the target format is handled deliberately rather than by accident.
When the source describes a color outside the target's gamut, chroma is reduced in OKLCh while lightness and hue are held, following the CSS Color 4 gamut mapping algorithm. Clipping each channel independently would be simpler but visibly shifts hue on saturated colors.
