CRT Bezels... grey or green?

[Charlie]

Something I've noticed about color roundies... It seems that the bezel around the CRT is either green or grey (especially on RCAs). Does anyone have a theory as to how they decide which sets got which color bezels?

Here is a theory I had considered. It seems that 21FJP's have somewhat of a green tint to them with the glued on safety glass. Out of the FJP's I have, they have the green tinted bezel.

On the sets that have FBP's and non-frosted safety glasses, those usually have the grey bezel.

Below are examples of a couple of CTC16s I have in the garage... one having green and one grey.

Does anyone else agree with this, or even have another idea between the grey and green?

Personally, I like the grey better.
