Plain black interpreted by Raphael, with everyone cycling in the foreground (7)
I believe the answer is:
llanero
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for llanero that I've seen before include "Liver on plain" , "Plain person" , "Plain dweller" , "Plainsman" , "Plains dweller" .)
