Some inside think yarmulke looks kind of dark black? (4)
I believe the answer is:
inky
'kind of dark black?' is the definition.
'inky' can be an answer for 'black?' (I've seen this before). I'm not sure about the 'kind of dark' bit.
'some inside think yarmulke looks' is the wordplay.
'some inside' says the answer is hidden in the clue.
'INKY' can be found hidden inside 'think yarmulke looks'.
Can you help me to learn more?
(Other definitions for inky that I've seen before include "Like the printing trade" , "Jet" , "Completely dark" , "Pitch-black" , "Like writing fluid" .)
