Something drawn by Titian is layered (6)
I believe the answer is:
tiered
'is layered' is the definition.
(in multiple tiers or layers)
'something drawn by titian' is the wordplay.
'something drawn' becomes 'tie' (a tie is draw in sports).
'by' means one lot of letters go next to another.
'titian' becomes 'red' (Titian can mean a red colour).
'tie'+'red'='TIERED'
(Other definitions for tiered that I've seen before include "Ranked" , "Cunstructed in layers" , "Arranged in levels" , "Arranged in layers like big cake" , "Laid out in layers, like wedding cake" .)
