Opposite

On The Beast, I went with a red display for my radio and a blue bowtie.

 

Marv has gone with a blue display and a red bowtie. 

We laughed at that.

For me the radio is red because I couldn't find a brightness setting with the blue that I liked while driving at night.  Marv stayed blue because red means warning and would keep distracting him.

For the bow tie, it's an old tradition.  Red is the performance color and Marv has had a red bow tie on his Impala SS for as long as we can remember.

The Biscayne SS got a blue bow tie because I wasn't aiming at "performance" but a phantom of a car Chevy never made.  The Biscayne was either a stripped down fleet car; or it was the top end luxo-barge.  There was never a super sport version, so I stayed with the more mundane color.
