Is it possible to give a color temperature for light that has been filtered?
At work we have a clean room with yellow light that has been filtered to remove blue and UV components because we process photosensitive materials there.
Now our safety inspector asked me to specify the color temperature used and I am wondering whether it is at all possible to give one for such lighting. My understanding is that color temperature is the spectrum of light emitted by a black object when heated to a certain temperature. And no black object will emit a partial spectrum. But as I am not sure my grasp on the physics is correct I want to know:
Is it possible to give a value and which would it be for white light with the UV to blue bands (everything < 500nm) filtered out?
