Colour during policy announcement (4)
I believe the answer is:
cyan
'colour' is the definition.
(greenish blue colour)
'during policy announcement' is the wordplay.
'during' indicates a hidden word.
'CYAN' can be found hidden inside 'policy announcement'.
(Other definitions for cyan that I've seen before include "Blue printing ink" , "Blue-green colour" , "shade of blue" , "Printer's colour" , "Bluish-green" .)
