As a fellow Bruin, I get pull for yellow tape. It would be okay, but it would not be my first or even second or third choice.

I'll add another possibility - black. Black bar tape is never wrong. Ever.

White is another good option for your bike, but white shows dirt pretty much two seconds after you put it on. Silver or grey would okay for this one also as it would pick up the color of the Univega decal.

Blue would not be a good idea. If you match the frame color exactly, it looks too machy-matchy. If you can't match the frame color exactly, it just looks bad.

Those are my thoughts and, as usual, my opinion is worth exactly what you are paying for it. :-)
