Subject: UFOs Over Phoenix: Dilettoso color analysis

I have been trying to figure out Jim Dilettoso's color analysis,
as presented in the Discovery Channel documentary.  It was not
very clear to me, but I presume that someone here on the list
knows more about it. My basic problem is with video color
analysis of an object whose color in the video is clearly wrong.

According to all the witnesses, the 10pm lights were amber or
orange. But on the videos, particularly the Mike Krysten video
that is commonly shown, the lights appear white.  I presume that
this is not because everybody's white balance was way off, but
because the lights were so bright that they exceeded the maximum
brightness capability of the camera.  When this happens, the
"white clip" circuit in the camera would be activated and would
produce a constant white output, instead of the real brightness
and color of the incoming light.

So then Jim Dilettoso analyzes the video and finds that for these
lights the red, green and blue portions of the spectrum all line
up exactly, and this is different from the spectral signature of
normal lights, including flares.  The brightness of the lights
also doesn't vary, as one would expect if they were flares.  But
isn't this spectral signature and lack of brightness variation
exactly what you would expect for a pure white produced
internally within the video camera by the white clip circuitry?
