Alternative... get black dye, use it to touch up any spots where the colour has faded. After that's dried, apply dubbin (Mink oil) all over the glove, then blow with a hair dry till it all soaks in. Repeat until the oil takes longer to soak in. They'll be nice and black, and reasonably water resistant. Do the same thing with your arctic mitts (Well, ignoring the dye part anyway).
