Yes. A (regular) RGB LED is simply 3 LEDs in single package with a shared anode or cathode (there are 4 leads). You change colors by adjusting the brightness of the 3 LEDs. And, if you can dim one LED you can dim 3.

But of course, you need three output pins and three 0-255 PWM values to get the full range of colors/brightness.
