Tint like turquoise (4)
I believe the answer is:
aqua
'tint like turquoise' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aqua that I've seen before include "Water (L)" , "(Denoting) water (Lat)" , "Prefix denoting "water"" , "Water; pale blue colour" , "which supports boats?" .)
