The two main colours of concern along Kelvin scale

hello,

I was recently asked in an interview for video editor,
"Which are the two main colours of concern along the Kelvin scale?"
Green and Blue
or
Red and Green
or
Black and white.

I never came to a situation like the above before, and i was wondering if anybody can give me an answer and why please.

I pressume this has to do with possible clipping or colour wavelengths that video cannot record properly ?

Any answers will be appreciated
Thanks

Very odd question. The Kelvin temperature scale normally goes between amber ( Kelvin white balance is too high ) and blue ( Kelvin white balance is too low ).

As for color channel clipping it depends on the camera you are shooting with.

In terms of real-life video color reproduction, red has traditionally been one of the most difficult colors to get right.

It is a weird question.

Primary colors are measured by frequencies or wavelengths. The Kelvin scale is however a temperature scale. Light can be indirectly associated with temperature by heating up some source (low temperature goes to the red while high temperature goes to the blue).
