Colour of a clumber spaniel (5)

I believe the answer is:

umber

'colour' is the definition.
(umber is a kind of colour)

'of a clumber spaniel' is the wordplay.
'of' indicates a hidden word.
'UMBER' can be found hidden inside 'clumber spaniel'.

(Other definitions for umber that I've seen before include "Deep brown" , "Earthy colour" , "Natural colouring matter, dark brown" , "Dark brown (pigment)" , "Yellow-brown pigment" .)

I've seen this clue in the Evening Standard.
