Like the AppleFritter site, Apple has finally figured out for iOS 13 that a black background with lighter (white) text is easier on the eyes. Hmmm, if only there had been a computer with that format... oh I don't know, maybe 42 years ago?! Now I need to look for the setting that allows the text default color to be green...Seriously, it took them 13 iterations to remember this?!
