Colour used in painting experimentally (5)

I believe the answer is:

tinge

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

'in painting experimentally' is the wordplay.
'in' says the answer is hidden in the clue.
'TINGE' is hidden within 'painting experimentally'.

'used' is the link.

(Other definitions for tinge that I've seen before include "Smattering" , "Colour slightly; trace" , "Slight colouring" , "Slight but perceptible amount" , "A colourful" .)

I've seen this clue in The Times.
