While yes after 1914 and before 1926 all T's were painted black because the paint dried faster. That is only part of the story. With the high volume of T's being made there really wasn't time to paint other colors. Remember also, that for most of those years, paint was not sprayed on. Parts were dipped and the body paint was hosed on so for the body you would have had to have several different painting lines, one for each color. Also, with all the wood structure till 1926 models, cars could not be oven dried like fenders, hood etc.
As afar as non original colors on an A. It's your car enjoy it as you like. Personally I find the original colors for the most part are not that great. With the falling number of people going for high points restorations and age changing demographics, brighter colors might have an advantage. Like the colors on Bob's and that red/black coupe.
