Yes. Black. I think it'd be interesting for people to post "why" it's their favorite color. Does the particular color illicit a fond memory, etc?...
Mine is black. If you're a musician you'll understand. If not, basically as a professional musician, everything you wear is black, music folders are black, etc. Any performance is usually set against black on black, etc.
+1. Black is my favourite colour, and I'm a musician
