This problem might be because 256-color/16-color bitmaps don't use RGB values. May be they use palettes somehow.

You are correct, obviously you cannot put RGB(R, G, B) into 4 or 8 bits. The early bitmap types could select a subset of the RGB spectrum and did so by first selecting a palette of colours and then using the color value as an index into the palette set. So the bottom line is that you cannot use all the new functionality with the old 16/256-colour bitmaps.

Can you give an example for using a palette?

The book Programming windows of charles Petzhold explains it pretty well
