I really can't stop messing with Emerald for the last few days and I thought I'd share the colors of the rainbow. I took the earlier posted color settings, tweaked them a bit, and took pictures with the same methodology/camera to try and show what a single Emerald saber can do. All of these are just my interpretations and utilizing the work of others in this thread, and I am totally new to all of this, but thought this could be useful to others.
Photo conditions - against a white painted wall, standing vertically. Lights off, no flash. Camera is iPhone 5.
Saber is a Archon 2.1, UltraEdge midgrade blade, with an RGBW LED and 4 channel driver without AV switch (all 4 channels available).
Not sure about the photo sharing etiquette here so I'm just going to share the first one and then link to photobucket for the rest (the photos are labeled). Note that some of the colors really do look the same as photos, but not really in person, and some even counterintuitively so - as an example, for some reason "Emerald Green" looks bluer in my photo than SRD but in person SRD is definitely more blue.
Guardian Blue
For the rest of the colors:

One note I've found - Blue is potent stuff. At least on my saber, a little bit of blue can go a long way in making a color more, well, blue. It's telling to me that the best way I've found so far to make Arctic Blue is to use more green than blue - it just overwhelms the green. At least to my eyes.
Some other notes I've found on pulsing and FoC - I've found an easier method for pulsing than I originally was using - if you have White available, and you aren't using it, just strobe it at 0-0.02-0-0.02 with it low (I like it at 0 and 20 for Guardian Blue). I think I like how this looks better, and it's simpler to tweak as you aren't messing with the color LEDs.
As for FoC - there's lots of things you can do here. One neat thing to try is to flash RGBW at 255 across the board - what ends up happening is you see a flash that seems like the colors you *aren't* using in the base color mixed in with the white - not sure if this is optical illusion or real.
Recently for FoC I've become partial to just flashing whatever my base color is + White 255. If you just flash to White only, it has a more jarring effect, whereas just flashing white on top of the base color seems more natural and blends better while still having the desired effect.
I really like FoC on 0.1 - 0.1 Play 1 time.
