Venetian Renaissance painter (6)
I believe the answer is:
titian
'venetian renaissance painter' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for titian that I've seen before include "Reddish-gold; painter" , "Italian Old Master and colour" , "Italian painter, d. 1576" , "Venetian painter - shade of red" , "Italian painter; hair colour" .)
