Couldn't we use something like KL divergence to measure the difference between a given bulb's spectral distribution and a perfect black body?

- Zak 8y agoThere are several other ways color rendering can be measured, but the ones used in the lighting industry tend to be based on comparing the rendering of specific samples much like CRI. One that's seeing a lot of use lately is IES TM-30, which is based on a much larger number of samples and includes a measurement of color gamut as well as fidelity.
