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?

Easier to mask manufacturing defects.  I wanted wood color 803's but could not pass up a deal on black ones.  My 40 year old stand mount B&W's are much better looking, with beautiful wood.
Black speakers and components are unobtrusive for sure and that's  great if that is what you're going for.  I know the feeling and have spent many hours staring at a flat black AR Ref 6 with the blue/green display.  That said, I recently purchased Dartzeel components which are gold and red and Evolution Acoustics speakers that are a beautiful red with black fronts.  Most of you know the sound quality from these components is spectacular but what I would like to add here is the use of bold colors really add to the appearance of my room.  I wasn't sure at first if I would like that but now I would not have it any other way.  In a word they are a joy to look at as well as listen to.         
black plastic is cheaper to produce, and for metal paint is cheaper and more practical than white ..

It's easier, for me, to see past a black component or speaker and concentrate on the music. Can't speak for others of why black polls so popularly with Americans but it does. Funny how we create mountains out of mole hills.

All the best,
