Moderated, with "down" (5)
I believe the answer is:
toned
'moderated with down' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for toned that I've seen before include "Noted (anag.)" , "pitched just right" , "Muscular" , "Slightly tinted; firm-muscled" , "Braced" .)
