I was under the impression the Jade cast was the only female ornate cast(Lanque not withstanding)?Regarding Fuchsia bloods, if they are any males then perhaps they too were killed off to keep away ascension of the thrown? I really never thought about this but it's definitely interesting to ponder over!

Ceruleans and Purples are also told to be mostly male-leaning Castes, so there may be some fuchsia nuance, but again, we’ve seen very few Fuchsias for obvious reasons.
