Paranormal anti-green colour (9)
I believe the answer is:
tangerine
'colour' is the definition.
(tangerine is a colour)
'paranormal anti-green' is the wordplay.
'paranormal' indicates an anagram (the letters in an abnormal order).
'anti'+'green'='antigreen'
'antigreen' is an anagram of 'TANGERINE'.
(Other definitions for tangerine that I've seen before include "Tree" , "something juicy being given to press" , "fruit product" , "Orange-type fruit" , "Small orange" .)
