Really, my opinion on the color of bar tape can be ignored, easily. I'm pretty grumpy snoby dude with taste no one understands (don't mind non-matching blue tyres with purple frame, only blue ones were available in the shop at the time of purchase, it's temporary). What I'm saying on celeste is that Bianchi swear by this color. They use it so extensively that it became the signature of the brand, so anything non-Bianchi in this particular color automatically makes one think about that brand. However, I've seen Bianchi bikes in purple and in red and IMHO they looked way better than in celeste.

For your particular bike I'd choose simple white or black. It will look classy. And by the way, soon you'll understand what a head-turner you have!
