Change colours of Screw Caps in Product Photos

I need a quick, precise edit to my product photos. The screws in the photos have bright red caps; but we have updated them to be knurled stainless-steel so I need the photos updated. There are two product photos to update, and I will provide photos of the knurled stainless steel for reference...
