> Like all settings, the color of light has a unit associated with it. The unit, however, isn't unique to specifying the color of light. Instead, it's the same SI unit that is used for temperature: the Kelvin. I know that the first few times I delved into this subject matter, I thought it was a strange unit to use, mostly because light itself doesn't have a temperature. Since it's radiation, when it hits a surface it can cause that surface to heat up. But the light itself is neither hot nor cold. So, why the heck is a unit of temperature used to describe the color of it? ...
