Quite so. As a point of interest and I am sure you would know Tal, do we know what house teal tips represents? Do I recollect correctly that it was said somewhere that Icarians of specific houses are naturally attracted to certain other houses, like Royal Thrones and Imperial High Sepharims?

This passage from Book 2, Part 2, Chapter 31 might give a little insight to teal, and some of the other colors mentioned. This comes from when Jamie is invited to visit Hippolito.
Walking into the room, Hippolito’s wings caught both the sunlight and Jamie’s immediate interest. The distractions at the party during his brief conversation with Hippolito hadn’t allowed him a thorough examination of the boy’s wings. There were many different hues, tones and color combinations an avionne could have, but a series of standard patterns separated the race into specific classes such as Thrones, Royal Thrones, Seraphim, Principalities and Powers, along with a wide variety of others. After years of living in Küronas, Jamie had learned that some classes of Avionnes – such as Cherubim and Principalities – were more common, while others like Royal Thrones and his own class of Imperial, were much rarer. Looking at the young man’s wings, Jamie couldn’t easily place him in any one of the standard Avionne categories.
While Hippolito’s wings were largely white, the edges of each feather had bluish-green highlights that bordered on teal with markings in the standard pattern of a Principality. But unlike typical Principality markings, closer examination revealed that where the white and teal color met, there appeared to be the thinnest line of iridescence at the point of the color blend; A feature that to some extent mimicked his own Imperial markings. The boy drew closer and Jamie became even more intrigued when he noticed that each one of the boy’s feathers was tipped in a tiny bit of gold; One of the principle traits of a Royal Throne.
As far as the second part, I don't remember seeing anything about attraction.
