Com fio aponta a lógica da Guarda Arco-Íris nos livros, e a razão pela qual não é usado / nome no show:
A Rainbow Guard makes a certain amount of sense within the context of Westerosi society, whose dominant religion uses the rainbow to symbolize the seven aspects of God, but a Rainbow Guard strikes many readers as a distracting, fourth-wall-breaking gag about Renly’s sexuality.
Adicione também que a Guarda Arco-Íris foi criada para contrastar com a Guarda Real vestida de branco.
Embora não seja possível confirmar diretamente a fonte, este relatório de uma convenção parece apoiar o Reivindicações do wiki:
The Rainbow Guard isn't meant to symbolize Renly's sexuality. It was more of a culmination of several unrelated things, such as the fact that he'd already used white for the Kingsguard and black for the Night's Watch. A rainbow is seven colors combined together in one object - he compared it to a shamrock being a Irish Catholic symbol of the Holy Trinity, three parts which make up one thing. Plus it has seven colors and is tied to the Seven, plus worshipers of the Seven use prism rainbows in their temples.
Martin afirmou que a relação implícita entre Renly e Loras foi intencional - então seria surpreendente se ele, então, decidisse negar intencionalmente fazer uma implicação adicional com o uso do Rainbow Guard.
George specifically stated "Yes, I did intend those characters to be gay." Not that we didn't already know that of course, but I don't believe it's ever been actually confirmed before.
