Thread: Tri-cree XP-E2 yellow?

    What sound card are you using and what main color are you planning on having? Red and Green can be combined to a decent yellow, the thread here is a bit old, but it describes colors with which you might be able to make a brighter yellow.

    If you are using a card that adds the flash to the main color (pico crumble, nano biscotte), the only way that could really work is to add red to green, or green to red.

    Yeah I plan on using a nano biscotte v3. Do you know what resistor I should use to get as close as possible to a true yellow? Or is a resistor not needed? Thanks

    You will need resistors. "true yellow" is a bit subjective, but if you are doing red+green you can get a pretty good yellow by using the full power red and green. The resistor values need to be calculated based on the forward voltage, amps, and power source. If you are doing a red or green main blade color you can make your third LED amber so that the flash will be red+green+amber which should be a very nice yellow.
