A color temperature selector for a television receiver which can select a color temperature using electrical control signals. The emitter of a drive transistor is fixedly connected to one resistor which is connected in parallel with two selective resistors to change the emitter resistance value. The two selective resistors are selectively connected to the fixed resistor using general semiconductor switches. This arrangement allows a remote controller to select a color temperature by a control signal, and allows to select a desired combination of color temperature setting states.
