what you see is essentially a convolution of the spectrum, of the object
with the spectrum of the slight source. which is often called simply
"color of the object".
does this settle the subject?
Nope -- because you've left out the receiver! (As in my white
balance experiment.)
Your brain translates the "colours" you see into the "colours"
you expect to see. That's why we see much the same colours with
daylight, tungsten, etc. but the camera "sees" things quite
differently.
