You forgot gloves??? Yikes! When I've gotten haircolor on my skin in the past I've gotten out the Comet cleanser (or Ajax or whatever you have in the house), added some water to make a paste and then scrubbed away at the area. You might also need a nail brush (or an old toothbrush) for your nails, though, since I'm sure the color will stain the nooks and crannies.
Hope your hair turns out gorgeously!
