Style of painting embraced by Picasso particularly (2,3)
I believe the answer is:
op art
'style of painting' is the definition.
(optical art is a type of painting)
'embraced by picasso particularly' is the wordplay.
'embraced by' says the answer is hidden in the clue (surrounding letters embrace the answer).
'OP-ART' is hidden within 'picasso particularly'.
(Other definitions for op art that I've seen before include "1960s' style of abstract painting, with dramatic visual effects" , "Abstract geometrical genre of painting" , "that may give the illusion of movement" , "Illusory visual form" , "Style of painting having an illusion of movement" .)
