In similar fashion to the PolarFLO Universal block before it, the TT block is available in multiple colors. The differences are that there are currently fewer of them, and it is as a two-tone design. Currently they are shipping blocks with 4 finishes; chrome (pictured above), chrome/red, chrome/black, and chrome/blue. To be honest, the new appearance options are pretty darn sharp. The two-tone look provides a nice contrast with the chrome.
