Throne helpfully implemented the selective spoiler thing, so I went with the first one. :)

Yay! Thanks, Kappa and Throne!

███ Guilty: Palatinate, #682860 (Pine, #01796F)

I'm reasonably confident this won't be confused with Jarn's (the primary is only slightly different, so it could pose conflict, but the secondary is green instead of blue). The primary is Palatinate #682860, which matches with my secondary (also Palatinate #682860).

Comparison:
███ Anya: Lavender, #C080FF (Silver, #A0A0A0)
███ Guilty: Palatinate, #682860 (Pine, #01796F)
███ atheistcanuck: Plum, #7D0552 (Redwood, #A45A52)
███ Jarnvidr: Tyrian, #4F012E (Ultramarine, #3F00FF)
███ Timepoof: Rose, #FF91BF (Chocolate, #692823)
███ AndaisQ: Pink, #FF4080
███ Throne3d: Carmine, #960018 (Palatinate, #682860)

If Kappa's happy with it, I'll add it to the rainbow and report.

I have successfully managed to figure out how to merge a pull request on github, go me.

Woo! The rainbow is updated. (The report will have more moieties tomorrow.)

Attempting to pick a moiety colour. Any objections to this one?
███ Kaylin: Royal, #1800DB
Also, does anyone want to suggest some secondaries, possibly in the gold-brown colourspace?

Bunch of suggested secondaries, plus a suggested alternate shade in case that turns out nicer, pulled from a previous use of Royal as a suggestion that was never grabbed:
The slightly paler Royal seems to go better with most possible secondaries. I think my standout favourite here is this one:
███ Kaylin: Royal, #4169E1 (Stormcloud, #AAB7BF)

It also looks good with your original proposed shade:
███ Kaylin: Royal, #1800DB (Stormcloud, #AAB7BF)

Apart from that, some of the ones I think look best:
███ Kaylin: Royal, #4169E1 (Smoke, #693834)
███ Kaylin: Royal, #4169E1 (Shale, #564D48)
███ Kaylin: Royal, #1800DB (Chocolate, #692823)

And of those, I'm leaning towards option 2. ███ Kaylin: Royal, #4169E1 (Stormcloud, #AAB7BF)

Checking against surrounding colours: Yup, works. Thanks!

Added!
