Awire from the power supply is carrying 120w of power and 24a of current. which color(s) of cable is the wire

There is no picture given so I can't be really sure what color of the cable you're referring to. However, the only relationship I can think of when the power and the current is given would be: P=IV or P = I²R, where P is power, I is current, V is voltage and R is resistance. Solving both equations:

120 W = (24 A)(Voltage)
Voltage = 5 V

120 W = (24 A)²(R)
R = 0.2083 Ω

So, i think the cable would have specification of 5 Volts and 0.2083 ohms.
