Use curses. All other approaces puts you in deep whater once your
program is run from different kinds of terminals.

Use curses.
If you absolutely do not which to use curses, then you can usually
change colors by sending the appropriate escape sequences. Most
terminals (including Linux console) accepts the standard ANSI escape
sequences.
<ESC>[3<n>m changes foreground color to color n
<ESC>[4<n>m changes background color to color n
<ESC>[<y>;<x>H moves the cursor
<ESC>[0m reset to normal text

----- curses example
#include <curses.h>
int colors[]={
COLOR_WHITE,
COLOR_RED,
COLOR_BLUE,
COLOR_GREEN,
COLOR_YELLOW
};
int main(int argc, char **argv)
{
int i;
initscr();
start_color();
for(i=0;i<5;i++) {
init_pair(i+1, COLOR_BLACK, colors[i]);
}
for(i=1;i<=5;i++) {
attrset(i,NULL);
mvprintw(5+i, (5+i)*2, "Color %d");
}
getch();
endscr();
}
---- ansi escape example
#include <stdio.h>
int main(int argc, char **argv)
{
int i;
printf("\033[H\033[J");
for (i=0;i<5;i++) {
printf("\033[%d;%dH\033[3%dmColor %d",
5+i, (5+i)*2, i, i);
}
printf("\033[0m\n");
}
