A/N: some research on Elven heraldry shows that Elwë's devices had silver and blue in them. I'm giving Losgael a minor noble ancestry. Though she is related to a great Elven king, she is not directly descended from him or anything. She's like a distant cousin. If she was English, she would be “The Honourable Losgael.”
Glorfindel's heraldic colours are actually green and gold. I'm also going with the idea of Glorfindel as the Balrog-slayer.
