Red fluid leak?

[cetane]

I just noticed some drops of red oily fluid in the snow this afternoon. The leak was basically under the front of the car, more or less centrally located. Does red indicate power steering or front differential fluid? I'm a bit worried because the dealership is 50 miles away and I don't know how long this has been leaking. So if it's front diff I'd rather not drive it that far because who knows how much has already leaked out.
