Reply to comment by ChronoKing in Is there a consistent and objective way to assess the color of an object? A transform function from spectrum to RGB, maybe? by DJTilapia

I believe you mean "specular" for "spectral" in the above.

Spectral measurements provide light intensity vs wavelength (or 'color') while specular measurements are of color including surface 'roughness'.

Beyond Hunter labs, a great read for beginner or experienced person is https://en.wikipedia.org/wiki/CIE_1931_color_space

Came here to link this. I am fairly certain that Hunter Labs only use the color space, it was defined by the International Commission on Illumination.

Nearly every major company that makes images or displays use this, such as Polaroid, Kodak, LG, and Foxconn to name a few.
