Colour given in 'Chambers' (5)
I believe the answer is:
amber
'colour' is the definition.
(amber is a kind of colour)
'in chambers' is the wordplay.
'in' indicates the answer is hidden within the clue.
'AMBER' is hidden within 'chambers'.
'given' acts as a link.
(Other definitions for amber that I've seen before include "Orange traffic light" , "Name of female" , "Prepare-to-stop signal" , "Yellow-orange" , ""Stop" traffic light" .)
