FWIW... I love my Imola Yellow TSM-MX!!! Yes, the color is a VAG (Volkswagen Audi Group) color. It was one of the few colors available on the 2003 20th Anniversary Edition VW GTI if you want to get specific.
My main listening room is kinda dark (not much natural light) so the color of the speakers stands out nicely ;-) and they sound great too! The pictures do not do the speakers full justice. The color does not distract me from listening and has not seemed to bother the customers that have seen/heard them in my room.
Anyway, its hard for me to pick a favorite color, but I have been bugging Bobby to do a pimped out VSM-MX in Piano Black with chromed rods, esotar tweeter faceplate, and logos :-) :-) :-)
