ravenclaw
When the eagle crest or the colors of Ravenclaw house are featured in a Harry Potter post. The colors are blue and bronze or blue and silver and are often found on clothing such as neckties, scarves, socks, and the hems of sweaters and robes, and on furnishings such as banners, rugs, and pillows.
This should not be used when a post features a character who is a member of Ravenclaw house (such as Luna Lovegood) but not any house colors or regalia.
