Pigment seen in fancy animation (4)
I believe the answer is:
cyan
'pigment' is the definition.
(thesaurus)
'in fancy animation' is the wordplay.
'in' says the answer is hidden in the clue.
'CYAN' can be found hidden inside 'fancy animation'.
'seen' is the link.
(Other definitions for cyan that I've seen before include "Bluish green" , "Bluish-green" , "Blue printing ink" , "shade of blue" , "Primary blue colour in printing" .)
