* One of WABC Channel 7 New York's Ikegami HK-312C cameras, as of 1983, had similar artifacts, only magenta-ish; that was on a 1983 Eyewitness News opening teaser that has since been taken off YouTube.

OK, in all that smear, oversaturation, tape artifacts and MPEG artifacts, what emerald greenish artifact do you mean? Are you pointing out the forehead highlight that is clipping and turning greenish, or something else?

I'm referring to the top- and bottom-most edges (at left and right) of the screen in those time positions (circular in nature, probably the edge of the lens; reminds me of circular edges of camera lens in B&W TV cameras where there's black on the "outer" part of the frame). B.T.W., the "oversaturation" may've been attributable to its having been recorded off the air at home. Professionally recorded (i.e. at the station) material would've had color as subtle as that 1958 WRC studio dedication.

And here's what I mean (with arrows pointing to the areas in question):
