Blue and White Coax for MIMO

Depending on the type of DAS platform (i.e., SOLiD, Andrew, MobileAccess) you are deploying, if it's a MIMO DAS you may have to pull parallel cable. For those who are not familiar with MIMO deployment, you will have to pull two sets of coaxial cable, splitters/couplers to a pair of antennas at the same location only 4-6 ft apart. In the field, this may become little complicated, because you don't want the parallel cables to get crossed. Installers usually mark the tip of the cables before pulling so that they can differentiate the cable sets.

One idea might be using cables of different color. So for example, you can pull a set of blue coax, and white coax as parallel network. I am strictly looking at it from the perspective of reducing confusion; however, logistically this may become a little complex - especially if the two colors of coax are produced by different manufacturers, etc.
