On Tuesday, President Bush invited President-elect Obama and former-presidents Clinton, Bush, and Carter to the White House for a lunch and a lovely photo op:


In photo ops such as this, I always wonder if aides to the gentlemen consult what color of ties the other gentlemen are planning to wear.   The two Bushes and Obama all are wearing a nearly identically-colored ensemble, but if you switch out the tie colors, a little variety and separation would be present.

Even in presidential debates, do both campaigns coordinate the tie colors as part of the myriad of rules for the debates?

Or am I overthinking this? :-)
