He takes turn in shade (3)
I believe the answer is:
hue
'shade' is the definition.
(both can mean a colour)
'he takes turn' is the wordplay.
'takes' means one lot of letters goes inside another.
'turn' becomes 'u' (a 'U-turn' is a kind of turn).
'he' going around 'u' is 'HUE'.
'in' is the link.
(Other definitions for hue that I've seen before include "appearance" , "Delicate shade" , "Shade of colour; Vietnam port" , "General hubbub - . . . and cry" , "Tone, shade" .)
