Your label's different colour (5,4)
I believe the answer is:
royal blue
'colour' is the definition.
(royal blue is a kind of colour)
'your label's different' is the wordplay.
'different' indicates an anagram (letters placed in a different order).
'your'+'label'='yourlabel'
'yourlabel' is an anagram of 'ROYAL BLUE'.
(Other definitions for royal blue that I've seen before include "Deep rich shade of colour" , "A shade Conservative" , "Queen's shade?" , "Your be-all (anag) - shade" , "(Regal?) colour" .)
