It's always seemed weird to me that Klingons and Romulans both have green ships. With Romulans it makes sense: Romulan blood is green, and they want to appear scary. With Klingons...they want to scare Romulans?
So, in TUC, should the Klingons have been flying pink ships?
That would have made an impression!
Koloth would have loved it.
