And [He has subjected] whatever He multiplied for you on the earth of varying colors. Indeed in that is a sign for a people who remember.
The following excerpt is taken from “Anwar al Bayan” vol 5 pg. 180:
“Thereafter Allah mentions a fifth sign saying, “And the things that He has created for you upon the earth have various colours.” Another translation of the verse is that Allah has created things of different types on earth. These will include every creation of Allah upon the earth. They are all placed on earth for the service of man. They are used to feed him, to construct his homes, cure his diseases, etc.
