It keeps being suggested that without an observer there is no such thing as
color - for there to be color it must be perceived.  That old tree falling in
the forest . . .

Since there is no proof one way or another we have to settle for opinion at
this point.  For me, if the existence of color depends on being observed why
not take that position all the way to its end, to where there is no spectrum,
no waves of energy, no trees.  Without an observer there are no things at all.

I believe that things exist without observers.  Maybe that’s partly the reason
why I have trouble with a sensor not having a color gamut.  A camera sensor
isn’t designed to amplify sound waves.  It sounds absurdly obvious to say that
a camera sensor is sensitive to, um, color.

Does the eye distinguish color prior to the brain’s post processing?  Yes, the
eye has already begun the work of distinguishing color before the brain gets
involved.
