Mine is a medium brown colour. When I was very young, it was lighter and took on golden shades in the sunlight. I discovered that by looking through old photos.
it's either dark or light brown. sometimes it gets really soft and smooth and shiny and it looks really light, but other times it's just hair and it looks dark.
It's kind of a deep red with a bit of burgundy to it. People have called it all sorts of names, mahogany, wine, etc etc. But it's just a deep red with a hint of pinkiness, turns really bright red in the sun.
It'd dyed but since I am a natural ginger people still ask if it's natural.
