Quoted from wxforecaster:

Hello off-topic unwarranted criticism! Every recent Stern uses color matching GI to accent their plastics. How it looks is a matter of opinion, not to mention, it's my game! Last I checked, I can experiment with my own machine, no, or did I lost that American right as well? My WPPR ranking would suggest my skill level hasn't suffered one bit from the color of light bulbs in my games or those on location. In fact, it may have improved from the skill challenge! There should be sufficient overhead lighting so as the GI is not the majority of illumination onto the playfield, anyways.
I recently did a friend's TAF with COMET's purple passion in the lower GI and a violet trough light strip. Game looks amazing and our scores haven't dropped at all. Likewise, I think some accents of blue in the in-lane/sling area of TZ will work.
