Burned deep red (6)
I believe the answer is:
seared
'burned' is the definition.
(I've seen this in another clue)
'deep red' is the wordplay.
'deep' becomes 'sea' (I've seen this before).
'sea'+'red'='SEARED'
(Other definitions for seared that I've seen before include "dried up" , "burned" , "Scorched on the surface (6).[BO]" , "Scorched, singed" .)
