No no no, you dont know what your talking about (or maybey I dont ). mode 13H is capable of displaying up to 256 colors on the screen at one time, thus 8 bit color. You can change the palette for any of those 256 colors to an 18 bit value (6 bits red, 6 green, 6 blue) giving you a quite a few different colors to choose from. Its still 8 bit color, being able to change the pallete does not make it 18 bit (or 24 ?). David, I see what you are trying to say but thats not how different color modes are actually refered to.
