I am going to put black bar tape on mine as well. I don't care for the white. I love my bar phat and hadn't ever used it before - very cushy. What saddle do you have on there? The saddle that came with mine was the Specialized BG Jett and it was just too harsh for my sitbones. I love the way Specialized saddles perch you up off girl parts so I switched to the Specialized Avatar which has some gel. The verdict is still out as I got it late in the season - I've only gone 54 miles in it.
Yea, white gets dirty too quickly. It's so pretty... but not practical. Plus, my carbon handlebars are black, and the bar tape doesn't cover them completely. It would look silly to have black showing.

I put a Terry Butterfly saddle on it. I went with that color, because it matched and looked better.

The saddle that came with it... was like sitting on wood. I go credit towards buying a new seat by trading it in to the LBS.

I am not sure I will like the saddle... as I haven't ridden on it at all. But my other saddle hurt my sit bones, so it can't be any worse I suppose. And I do have a Butterfly on my tri bike... and it seems to be fine... although your sit bones don't dig into the seat when you are in areo position.
