Perhaps Titian nude for sketch again (6)

Ross

I believe the answer is:

redraw

'sketch again' is the definition.
(to sketch or draw again)

'perhaps titian nude' is the wordplay.
'perhaps titian' becomes 'red' (Titian red is a shade of red).
'nude' becomes 'raw'.
'red'+'raw'='REDRAW'

'for' acts as a link.

(Other definitions for redraw that I've seen before include "Design again" , "Adjust" , "Change" , "Pick over" , "Sketch again" .)

I've seen this clue in The Telegraph.
