Why does one VVG cable have one copper-colored core and one bronze?

I bought a cable Gostovsky VVG 2 * 1.5. When stripping the veins, I saw that one lived in the color of copper, and the second in bronze. Why is it possible to put it on the lighting of the room, as completely copper? The seller claims that the wire is copper, although different in color. Thanks for the clarification.

    If there is a normal ohmmeter, you can measure the resistance of each of the wires for interest, if it is different, then different materials are used. In general, copper in wires can darken over time. Type of bronze - i.e. darkened and blushed :? But if there is a darkening - then on all veins at once, usually. Perhaps this is a fake, try using a knife to clean the core itself, what will happen to its color?
