it's actually the compressed nerve that's responsible for the numbness, not the loss of blood flow.

There's gotta be some partial decrease in circulation, though, given that my fingers on the numb hand are usually colder than my non-numb hand when this sometimes happens to me.

Maybe a bit, but there would have to be a ton of pressure. Consider the fact we have to use a tourniquet to cut blood flow typically, and those hurt like hell.

Maybe. Could be the compressed nerve reduces vasodilation in your fingers. Could be that your finger only feels cold.
