Red, Blue, Green LED:
Upper Left: Using Logic Source to show the various colors by switching the sources on / off.
Lower Left: Using logic source and potentiometer to slide color and intensity of the LED color and thus the RBG LED.
Middle Right: Using two sets of Logic Sources to "add" color intensity of each color. Example: Red: Off, Off, Green: On, Off, Blue: On, On. Color Result: Light Blue. Why? Both Blue switches are on. No red, one green. So: R / G / B = 0% / 50% / 100%.
Upper Right: 6 buttons to change color intensity.
