Holi celebrant (5)
I believe the answer is:
hindu
'holi celebrant' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hindu that I've seen before include "Follower of great Indian religion" , "Most of the Indians are" , "Believer in an Indian religion" , "Man of religion" , "One expecting to be reincarnated" .)
