Okay, think about the gay ships you know. Here are a few that I know that fit the description. They are going to be my examples.

SnowBaz
Solangelo
Kitty
Keirark
Drarry

Now look at the similarities:
Simon: blonde/bronze, blue eyes, orphan, very powerful magick
Will: blonde, blue eyes, has magic
Kit: blonde, blue eyes, orphan, very powerful magic
Mark: blonde, blue eye, orphan, part faerie (magical creature)
Draco: blonde, hates his family, has magic

Baz: black hair, associated with death (vampire)
Nico: black hair, associated with death (son of the god of the underworld)
Ty: black hair, associated with death (he is tied to his dead sister's ghost, so..)
Keiran: blue-black hair, associated with death (the Wild Hunt steals from the dead on a battlefield (I think??))
Harry: black hair, associated with death (Master of Death, anyone?)

And there were more....
But yeah. I felt like I had to share that.
