Your uncontrolled variable is color - this is the experimental variable that you change in the experiment.





Controlled variables would include things like light intensity (you wouldn't want to test one color on a sunny day and another on a cloudy day, for example), angle of test surface with respect to the Sun, the method used to measure solar energy generation (a thermometer? If so, type of thermometer, placement on test surface, etc. need to be controlled).
