German article returns in colour (3)
I believe the answer is:
red
'colour' is the definition.
(I know that red is a type of colour)
'german article returns' is the wordplay.
'german article' becomes 'der' (definite article in German).
'returns' says the letters should be written backwards.
'der' backwards is 'RED'.
'in' acts as a link.
(Other definitions for red that I've seen before include "Bordeaux claret, for instance" , "- Cross; - admiral" , "Very angry, seeing this" , "Colour for a blusher" , "Colour of communism" .)
