Are you sure that you can mix iostream and conio functions like that?  I
program in C, but it seems that cout isn't going to care what settings you have
in textcolor--printf wouldn't, anyway.

If you're using conio, you might as well stick with it.  You can say, for
example,

#include	<conio.h>

int main(int argc, char *argv[])
{
    int n_text, c;

    cprintf("Hit a key to increment mode value.\n\r"
	    "(First textattr mode is black on black.)");
    for(n_text = 0; n_text < 255; ++n_text){
      textattr(n_text);
      cprintf("\n\rI can't believe it's not butter!  %d",n_text);
      if((c=getch())=='x' || c=='q')
	break;
    }
    textattr(7);
    if(c != 'x' && c != 'q')
      cprintf("\n\r(textattr 255 is white on white)");
    cprintf("\n\r");
    
    return 0;
}

/*
gcc -Wall -O example.c
*/

You could also probably use cout with ANSI escape sequences, as long as you
have ANSI.SYS installed.
