Rouge hit the nail in the head as far as things go. Their both professional vocals, theoriginal "Yamaha Standard" vocals that pre-dated VY1 and VY2, both released for V1 and worked upon at the same time. The list goes on. The two were literally made for each other.

Red and Blue are also seen as opposing colours, with blue being regarded as a colour linked to masculinity and red/pink is considered more female. So even their designs are meant to compliment each other.

even when CFM took over their handling they matched the pair to a different set of criteria then their own Character Vocal Series vocals Miku, the Kagamines and Luka. So they pretty much carried on this, Kaito is mostly a softer/whispered toned vocal in the V3 updates while Meiko is more power/solid. CFM also treats the pair as adults and even more mature then Luka is, who is a young adult.
