That's odd, it has never changed the color of my wine before but I think it's okay provided you used the correct dosage.

what should i do if i added too much sulfate? should i throw the must out?

I assume that you mean Sodium Metabisulfite, in which case, you shouldn't be using that for wine, it's fine for sanitizing, but in your wine you should be using Potassium Metabisulfite. Sodium Meta is purported to impart off tastes into the wine.

In any case, your sulfite level is around 125 PPM, way higher than it should be. Some amount of exposure to oxygen through splash racking will reduce the free SO2 in your wine, I have no idea how much splash racking it may take.
