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! :)
