Partly put in the shade (4)
I believe the answer is:
tint
'shade' is the definition.
(I know that shade is a type of shade)
'partly put in the' is the wordplay.
'partly' says the answer is hidden in the clue (part of the clue is used).
'TINT' is hidden in the letters of 'put in the'.
(Other definitions for tint that I've seen before include "A slighth shade of colour" , "(Softer variety of) colour" , "'Shade, tone (4)'" , "Quality of colour" , "Hue, shade" .)
