It's silver greyish but when it gets exposed to an atmosphere it will turn red because of the iron like your blood.
Akshually the Moon is basically dark gray / black, it has an albedo of somewhere around 0.12. This means it reflects around 12% of the light that falls onto it. This is comparable to blacktop asphalt as we see on roads in our daily lives.
Of course there are many different kinds of rocks on the Moon, so it would depend on what sort of rock you are looking at.
And as for the colors in this image, that is most likely due to something called chromatic aberration. This is an artifact of the lens used. For astrophotography some people use special lenses that don't suffer from this effect.
