Each manufacturer has a color code for the wiring in the circuit. The chart above shows the color coding for those wires connected to the compressor terminals. This color coding can be used to identify the compressor terminals when the letter marking is not visible. For example, when checking the compressor in an Admiral freezer, a glance at the chart will show you that the run terminal has a white wire connected to it, the start terminal has a black wire, and a red wire is connected to the common terminal.
