When I see scarlet and gold, well, first, I do think of Gryffindor, but then I think of the meaning and power behind the colors. Reds, to me, represents a commanding power and blood. What? No, I didn't just say that...While gold portrays brightness and a certain ethereal quality. The fact that it's heavy, thus making it good for smacking people with totally does not sway my opinion what-so-ever!
Colors, all simple, yet, awesome elaborate forms of expression. I believe colors and symbols can have the same, if not almost identical, effect on people no matter how different the colors tend to be. When I see scarlet and gold, the Gryffindor house colors, I feel proud to be a lion, as I'm sure the members of my house and the other houses feel proud when they see their house colors. Scarlet and gold are associated with our daring and brave (verging on the side of complete recklessness) behavior, and I love it. In the books, scarlet and gold are associated with being brave, bold, daring, (the amazing Sirius Black because he's amazing) and so on and so forth, but on HOL, I've come to relate the Gryffindor house colors to that certain dignified insanity and the pure drive to confuse every living and non-living being that exists in HOL. I think we're doing a really spectacurally good job at it.
"You might belong in Gryffindor, where dwell the brave at heart, their daring, nerve and chivalry set Gryffindors apart."
"You might belong in Hufflepuff, where those are just and loyal, those patient Hufflepuff's are true and unafraid of toil."
"Or yet in wise old Ravenclaw, if you've a ready mind, where those of wit and learning, will always find their kind."
"Or perhaps in Slytherin, you'll make your real friends, those cunning folk use any means, to achieve their ends."
The characteristics listed above are representatives of each house and its colors, they are what makes each person into what they were chosen to be. Although, I truly believe Jo Rowling just simply forgot to add in "insanity" when listing the Gryffindor house characteristics as you would need to be insane to want to be in this house. Insanity is basically a prerequisite. With the colors each house represents comes the feeling of unity and pride for most. These colors are symbols that draw each member in the house together. In real life my room is very much of these colors, but that's just a handy side-effect of myself liking warm colors. If I feel the need to get dressed up, like a complete dork, and go to a midnight showing of a Harry Potter movie, you will, surely, find me in Gryffindor colors and not Ravenclaw, because Gryffindor represents the house I relate to the most, and find my home in.
Oh, and because we're basically the best house ever to walk the face of the planent. Ever, in my opinion. No point in arguing, you'll just end up losing, eventually. Scarlet and gold rock my socks!
