Tone adopted by cretin generally (5)

I believe the answer is:

tinge

'tone' is the definition.
(tinge is a kind of tone)

'adopted by cretin generally' is the wordplay.
'adopted by' indicates the answer is hidden within the clue.
'TINGE' is hidden within 'cretin generally'.

(Other definitions for tinge that I've seen before include "Colour slightly; trace" , "Little bit of colour" , "Hint; shade" , "A slight shade of colour" , "Hint of colour" .)

I've seen this clue in The Telegraph.
