changing text color

Hey ive been searching on the net on how to change text color but only come up with bitmaps, graphics like shapes. Can somebody please help thanx in advance

For MS-DOS you have to do something like:

#include <conio.h>
void some_function([parameters]) {

/* some code */
textcolor(BLUE);
cprintf("hello\n");
}


For Linux:

char yellow[11]="\033[1;33m";
/* etc */
