I quite like a lot of those colour variations.
GINO pushed VERY hard for that and at first it was something I resisted, but if you look at where many modern logos are going, they aren't necessarily sticking with a single color scheme and are creating logos that can be used in almost any color (USA Today and QVC's new logos come to mind). Sometimes I have to be dragged, kicking and screaming to accept these things, but this is why we went to a professional graphic designer this time around!
