Hi @esotheria-sims! Thank you so much for your kindness, I'm a little star-struck, because I'm such a huge fan of your BACC!

Yes, my plan was that magic has a genetic component, and for an easy way to see if a Sim had the potential to develop magic, I thought it could be handy to have some special eye colors (plus a good excuse to use gorgeous cc hehe). For eyes in general, I use @furbyq-sims's edit of mouseyblue's lucky mix eyes. And for mages in particular, I use the 'dragon egg' recolors (furbyq's preview pic):

Ezber had the bright green eyes, which most Cambremon spawns seem to have inherited:

Ezber's first wife, Nasbrin, (who hasn't really appeared, because I wasn't really taking pictures when I started Cambremon, oops) had nice purple eyes- Edvin had them too, and so does his daughter:

Andra also has 'dragon egg' eyes but they're a deep bordeaux tint, so not very noticeable- I think her son Carcic has those as well. My reason behind Andra having this eye color was that Andra, who looks nothing like Ezber, was actually the result of one of Nasbrin's affairs. Ezber suspected this from early on, and had zero qualms sending her off to the bloodthirsty Dantuzine:

Then you have the Dantuzine, who had cyan eyes- so does Iniga, Ezber's second wife. The reasoning was that Iniga was a distant cousin of the Dantuzine, and was actually chosen by Ezber because she had a potential for magic, even though she never became a Witch. Ferenia also has them, because she's actually Dantuzine senior's bastard, conceived during one of his 'diplomatic trips' to Cambremon:

And lastly, there are the 'orange' eyes- we haven't seen the Aramia clan much (once again, I don't have many pictures of my earlier days of playing Cambremon), but Ansyl Aramia, Edvin's missing ex-wife, has them. So do Kadja and her mother Eviya. To be honest, I just thought orange eyes looked nice on them, but let's assume they have some sort of distant ancestry with the Aramia hehe:
