Kelvin

Color Temperature

This is a one-way approximation. There is no .to('kelvin') method option. This method uses trapezoid integration to sum the wavelength distribution of energy through a black body tensor. While an approximation, it is a rather accurate one, and based on real-world black-body radiation measurements. Temperatures above 10,000°K may be less accurate, but the method allows for temperatures up to 40,000°K.
