You cut too deep insinuating advocating sensibility.
The following code is guaranteed NOT to work- I
didn't have the allegro reference in front of me
when I wrote it, and I didn't even try to compile it.
But if I were trying to accomplish this conversion
its where I'd start.

Charles Terry

Char colortable[255]

pallete_convert(pal screenpal,pal flickpal)
{

RGB* SC[255];
RGB* PC[255];
int place,place2;
int bestvalue=0xffff;

setpallete(flickpal);
for (place=0;place<=255;place ++)getcolor(place,&PC[place]);	
setpallete(screenpal);
for (place=0;place<=255;place ++)getcolor(place,&SC[place]);
	// you probably would have to tweek the color value test below
for(place=0;place<=255;place++){
	for(place2=0;place2<=255;place2++){
		if( abs(SC.R-PC.R)+abs(SC.G-PC.G)+abs(SC.B-PC.B)<
		   bestvalue){
			bestvalue=place2;
			if (0==bestvalue)break;
		}}
	colortable[place]=bestvalue;
	bestvalue=0xffff;
}
}

color_flick(char* bmp,int size)
{
for(int place=0;place<size;place++)
{
	bmp[place]=colortable[bmp[place]];
}}
