Which of the following factors does NOT influence how many watts an appliance uses?

The factor that does not influence how many watts an appliance uses is related to the color of the appliance. The wattage an appliance consumes is primarily determined by its design and electrical specifications—specifically the type of appliance, the duration it is used, and its wattage rating.

The type of appliance indicates its intended function and energy requirements; for example, a toaster typically uses less wattage than a refrigerator. The duration of use naturally affects the total energy consumption but not the power (watts) at any given moment. The wattage rating, which is usually found on the appliance's label, directly specifies how much power the appliance needs to operate.

Color, however, does not impact how much energy an appliance uses. It is merely a visual characteristic that does not relate to electrical consumption or efficiency.
