I believe I'm correct, that both the 2 Meters and the Dial Face used the exact same color Gel Material from the factory, that there is no difference in color-hue. Somebody correct me if I'm wrong?
With Swatch Packs of gel material that can be bought, and also possibly using something like only the Cool Blue LED Festoon Lamps for the Dial Face with the Gels removed, one could achieve a considerable variety of colors, it's all personal choice of course.
I only swapped the Dial Face Festoon Lamps to Cool Blue LED, was a super simple swap with no further surgery required.
If in the future event I have a Meter Lamp burn out, then I might further experiment with Gel Material colors-hues at this location. The cocoon wrap will then have to be removed to replace those Lamps, which I'd of course change both out.
