Black has its place. Traditional photographic development labs, bat caves, and rooms suited to a sound sleep with melatonin abundant are examples that come to mind. As far back as my memory is retrievable and personal ownership of electronic gadgets was part of my life, black has been problematic. Recently, preparing for a trip to Arizona, I extricated the rechargeable batteries from my trusty Sony camera and placed them without issue into the charger. A couple of days later I go to replace said batteries and the question is which one goes positive up and which one down. Apparently Sony has marked this for me but guess what? They have chosen to mark the battery compartments, already black as anthracite coal, with black markings. If I could take a picture of this unique feature I would but my camera is not that flexible. It looks much like this:
Sony is not alone. I have owned innumerable devices that pose exactly the same problem, as I am sure you have. Is it not time for a smidgen of creativity on the part of electronic manufactures? The infrequent appearance of the rainbow should offer some inspiration. Have any of them seen snow?
