Colored.
I have 2 dark blue vinyl and one dark blue (aqua) plastic surrounds for '64 (no pad) style surrounds.
(one in my car and one vinyl and one plastic as "spares")
My '64 Special I had back in the 70's had a vinyl black surround. The car was black exterior and black and white interior.
Hope that helps. :)
(edited cuz I typed 65 and meant to type 64, my old boomer fingers are getting crooked and type whatever they want.)
