Why is black so popular for components?

A current post about the looks of gear got me thinking. How did black become the most popular color for audiophile gear? I can see it being popular for home theater where the gear might be at the front of a room where you want it as dark as possible but black was the color of choice well before home theater. Maybe it is as simple as people just like it but if that were the case I would think it would also be the most popular in other consumer items such as motor vehicles.  I remember when I wasn’t always fortunate to have a dedicated stereo room and my wife would ask me why I purchased black equipment because she thought it was ugly and I agreed with her but usually, I had no choice.  For manufacturers offering additional colors may be costlier but I am willing to pay for it. Fortunately , some companies that I like offer silver usually in the face plates which works for me. Odyssey Audio has numerous color options available for their faceplates for a nominal fee but as far as I know they are an exception.  A lot of speaker manufacturers offer different colors which is great, especially if you have to place them in a communal space like a living room.  So in summary why did black become the color for stereo gear ? How many of you would prefer color options?

Black is very popular because you can change stuff and wife will not notice as much.
Black is the second most popular color in automobiles. Second only to white by a very thin margin. White  23.9%, followed by black, at 23.2%. Next is gray and silver at 15.5% and 14.5%. 

My T+A HV gear is champagne a beautiful color - but all my other gear is black. Other manufacturers silver can be in very different tones and difficult to match. For the most part black components from various manufacturers seem to work visually.     
josephp -- I say let the components all be different colors. It show that your ears are in charge.  Not your eyes!
