If you have a truecolor image and absolutely need to get the actual color of a pixel, it seems like
you could create a 16x16 indexed color image from a part of the True Color image containing the
pixel(s) in question. Then you should be able to guarantee that the indexed sample has the
indentical colors to the True Color image. you can then use this function to get the color index of
a pixel in the sample.
Obviously, this would be an intensive way to get pixel colors, especially for a large image, but as
far as I can tell, it's one of the very few ways to do it right now.
