Quoted from CaptainNeo:

says the guy who has a shit LED explosion as his avatar. it's not an opinion. It completely ruins the purpose of the what the machine is designed for. it's designed to be played. To be able follow the ball around and play the game. when you use anything except white, it makes it difficult to impossible to play the game in any darker gameroom setting. Plus, the entire art package, is completely ruined. it's like looking at a color picture in a red photo developing room. Everything, and I mean everything will look like shit. not an opinion. Fact.
And I was actually trying to help you thread by telling you, that you would get more people interested if you did the LED's correctly. 99% of people understand and realize how important it is to have white GI's in the backbox and playfield. There are some newbs that havn't come to terms with it yet, and people on FB that don't play their games and just gaze at them from the other side of the room. That 1% really limits your buying market. You would have much more board appeal by doing them the correct way. Especially since you are asking a higher price tag.
