The grimoire is called Ethica. It's a very pretty one, with butterflies and flowers. The type of drop you'd expect from a place like Dohn Mheg... except it drops from Castrum Abania?? It has never made sense that the pretty Fairy-looking book drops from a Garlean castle, while Dohn Mheg's weapons barely look fae at all.
As for the ginger options, I think it just stuck because how pretty I think orange and green can look together, and it's not a combo I see too often in XIV. I've dyed my hair a couple times IRL, but the eye color I'd need contacts, and I hate contacts.
