If you want a bright yellow, go with the amber and green. Don't add red because the green counteracts the red in the amber...so adding red would get you back to the amber/orangy colour. Just happen to have amber, green, and red sabers that I tested the mixing with
The amber-green mix is a really nice yellow.
Here's the link that I had created when I was looking into the lack of amps problem. Big shout out to Jay and Baboon for helping with it.
