Changes the color of (4)

I believe the answer is:

dyes

'changes the color of' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for dyes that I've seen before include "Colouring materials" , "Colour" , "Stains" , "turns green, possibly" , "Colours (fabric)" .)

I've seen this clue in the USA Today and the Newsday.
