what is possible, from talking too one of my fabulous friends, is to get the green and red leds flashing at high speeds making it look orange but you can't have the red and green leds on continuously to make orange. The leds in the cluster total 14, 6 red and 8 green. Having both on continuously its obvious to see the red and green leds, unless it looks orange in your periheral vision????
You could also alter the brightness of led by changing the frequency or duty cycle of the led so maybe this could be incorpoated when looking into an orange colour????
Have you ordered the same cluster i have????
