I believe the answer is:
pink
'salmon' is the definition.
(thesaurus)
'provided by shop in kensington' is the wordplay.
'provided by' indicates a hidden word (the answer is provided within the clue).
'PINK' can be found hidden inside 'shop in kensington'.
(Other definitions for pink that I've seen before include "Pale red" , "Ros colour" , "Left-wing" , "Salmon shade" , "one's found in bed" .)
