Red artist? (6)
I believe the answer is:
titian
I believe this clue is a double definition.
'red' is the first definition.
(thesaurus)
'artist?' is the second definition.
(Titian is an example)
(Other definitions for titian that I've seen before include "The painter Tiziano Vecellio" , "Italian painter, d. 1576" , "Venetian Renaissance painter" , "Italian 16th-century painter" , "Colour named after artist" .)
