I think of Slingerland when I think of WMP
I think black Cortex when I think of Rogers
Red sparkle or blue sparkle for Ludwig
Dark wood stain for Gretsch (or bright yellow)
Camcos weren't even known to me, so I have no idea what color to associate with them! I would have to say that, now, I think of some natural wood color -like maple or mahogany colors.
Trixon or Vox -I always think of that light aqua sparkle color
Sonor -always Rosewood or Bubinga
Premier -??? I remember a light opaque purple colored set from when I was in college. They were Resonators. -hated them, btw! :)
