Andúril light with true rgb? (lemmy.zip)

Is there an andúril light with actual rgb aux lights instead of the resistor ones or the single colour ones? If no, is it even possible with the microchip they use? I know its a pretty limited chip.

The aux LEDs are ON-high/ON-low/OFF and not controlled via PWM due to power consumption concerns for indicator aux LEDs that are designed to be ON all the time. With PWM the MCU has to stay awake and it would draw the cell too fast, due to that aux LED PWM control has not been implemented.

With the T1616 there might be a way to do PWM with relatively low power consumption, but that hasn't been tried yet.
