Coloured, stained (4)
I believe the answer is:
dyed
This clue is a double definition.
'coloured' is the first definition.
(I know that coloured can be written as dyed)
'stained' is the second definition.
(I've seen this in another clue)
(Other definitions for dyed that I've seen before include "Changed the colour of fabric" , "Stained - coloured" , "Cloth is often" , "(Of fabric) coloured" , "Given a new colour" .)
