Policy analyst exhibits kind of blue (4)
I believe the answer is:
cyan
'kind of blue' is the definition.
'cyan' can be an answer for 'blue' (I have seen 'Greenish blue ' mean 'cyan' so perhaps 'blue' could also mean 'cyan'). I'm unsure of the 'kind of' bit.
'policy analyst exhibits' is the wordplay.
'exhibits' says the answer is hidden in the clue.
'CYAN' can be found hidden inside 'policy analyst'.
Can you help me to learn more?
(Other definitions for cyan that I've seen before include "Printer's blue" , "Primary blue colour in printing" , "Bluish green" , "Shade of green" , "Greeny blue" .)
