Say I'm standing over a sink filled with regular tap water,
we'll call it "water A". AND hold, in my hand, a glass also filled with regular tap water, "water B" over the sink.
If pouring water B into the sink of water A should result in a "splash",
which water would I most likely be getting hit with?
also, what role does height and depth play?
would dyeing the water help?

Probably a little of column A and a little of column B. Geometry of the sink and the depth of the water plays a part. Certainly using dye would be in the empirical tradition. You should also probably use high speed strobes ala Edgerton (http://web.mit.edu/Edgerton/www/HighSpeed.html).

From the classic "drop of milk" sequence in the above link, it looks like the initial splash is composed of A (the water in the sink). But I think what happens immediately after is that the displaced water rushes back, resulting in a center plume that would contain considerable amounts of B.
