I think what is happening is that when the slider is turned to the red side, it is like there is no resistor in series with the red LED, but a large resistor in series with the green LED, so the red LED lights up and the green LED doesn't. (If it is a different color, it may light up dimly.)

Yes where when there is more resistance the red led that uses less power will turn on and more, the green will turn on and green uses more power
The led is waterproof
