Thank you for your prompt reply. I agree
regarding adding anything of use, unless there is a correlation between
ability to perceive colors and another variable, e.go. - faint meteor or
LM perception. If there was a strong correlation, would that become a
factor in analyzing one's report data? Sorry if this is a silly
proposition, I'm fairly new at this.

Steve:
I'm not sure I understand your
question. I haven't done serious visual meteor observing for a long
time, (poor visual acuity), other than monitoring my camera fields when doing
meteor spectroscopy. As for faint meteor colour perception I quote from
D.W.R. McKinley's book, Meteor Science and Engineering: "Recent Super-Schmidt
studies (Jacchia, 1957) have suggested that the color index may be about -1
for fainter meteors, possibly because the peak sensitivity of the eye moves
toward the blue for fainter light sources (Purkinje effect)." Jacchia's
paper can be found in: 1957, Astron. J., 62, 358-362, On the color index of
meteors. I don't have a copy of this paper, but would be interested in
seeing it if you run across a copy.
