Can you do this same thing with a RGB Led as apposed to three individual LEDs?

Cool man. Students will really like this specially if you will enclosed it into a paper ball (origami) and then turn the lights off so they could make different lights. we could even instruct them to make cyan, magenta, yellow and other colors just by turning on and turning off some lights. they will appreciate the color theory.

But the LEDs each have their own max voltage... by using the same value resistor does this cause the blue to be dimmer when it is at "full brightness"?
I meant to say the red light to be dimmer
