Yellowish-brown paintings maybe recalled religious writings (6)
I believe the answer is:
tantra
'religious writings' is the definition.
(ancient Hindu or Buddhist religious writing)
'yellowish-brown paintings maybe recalled' is the wordplay.
'yellowish-brown' becomes 'tan' (yellowish-brown colour).
'paintings maybe' becomes 'art' (paintings are a type of artwork).
'recalled' shows that the letters should be reversed in order.
'art' in reverse letter order is 'tra'.
'tan'+'tra'='TANTRA'
(Other definitions for tantra that I've seen before include "Mystical Buddhist text" , "Sacred books" , "Magic text" , "Teaching" , "religious work" .)
