On the topic of the Bussard collector color... On the original iteration of the big E under Pike's command, when the collectors still had those spires on them, weren't they just painted red? I believe it was after "Where No Man Has Gone Before" that they replaced the collector caps on the model with the translucent caps with lights behind them.
Not sure dude, but good point. I'll have to go back and check The Cage eh.

Here's a page all about the original three-foot model used for the show with some original promo photos of it. Note the ones with just Spock in them.
