which are usually color-coded to show the ranges of wire gauges— or wire thicknesses, measured in AWG— that they can be used ...

You are measuring a voltage and a current. With a four-wire measurement, one pair of wires carries current to the device under test and the other pair of wires measure the voltage drop.
