Entering a different shade (9)
I believe the answer is:
tangerine
'shade' is the definition.
(I know that tangerine is a type of shade)
'entering a different' is the wordplay.
'different' indicates an anagram (letters placed in a different order).
'entering'+'a'='enteringa'
'enteringa' with letters rearranged gives 'TANGERINE'.
(Other definitions for tangerine that I've seen before include "Kind of orange" , "Taste" , "Orange-type fruit" , "orange colour" , "shade" .)
