I'm trying to get a set of colors so I can use text mode but
with a graduation from deep red->white->deep green. I'm using
a VGA and Microsoft C 5.1, the following code sets up the colors

long newcolormap[] =
{
	0x000000L, 0x00003fL, 0x0a0a3fL, 0x14143fL,
	0x1e1e3fL, 0x28283fL, 0x32323fL, 0x1f1f1fL,
	0x323f32L, 0x283f28L, 0x1e3f1eL, 0x143f14L,
	0x0a3f0aL, 0x003f00L, 0x3f0000L, 0x3f3f3fL
};

void setupvga(void)
{
	_remapallpalette(newcolormap);
} 

but I have to use the Norton Command Centre to change the normal
pallete colors (0,1,..,5,20,7,56,57,..,63) to sequential numbers
(0,1,...,15) as the colors at 20 & 56 .. 63 don't change. Does any
one know how to set the pallete colors like NCC does or alternately
how to set these colors over 16.
