I have not ever bought the same color Tano. I admit to being a freak for Tano's blues but I don't buy the same blue over and over. In fact, I felt blueberry was close enough to blueprint to skip it this fall.
(I likely will not be able to resist Berry Blue and Hawaiian Blue for Spring however!!!!!!!)
BUT since I have a blueprint Boogie I'll likely not buy a Boogie in any of the new blues.
