Reddish-brown and gold torch (6)
I believe the answer is:
auburn
'reddish-brown' is the definition.
(synonyms)
'gold torch' is the wordplay.
'gold' becomes 'au' (Au is the chemical symbol for gold).
'torch' becomes 'burn' (to torch something is to deliberately burn it down).
'au'+'burn'='AUBURN'
'and' acts as a link.
(Other definitions for auburn that I've seen before include "Name of Goldsmith's deserted village (6)" , "Golden" , "Red-brown hair colouring" , "Goldsmith: 'Sweet . . . . . . loveliest village of the plain'" , "Reddish-brown, hair say" .)
