It depends how you are going to display the file. If you are
writing it to a terminal window, there are a set of control
sequences you can send to the terminal which identify
limited coloration, including reverse video.
For example:
#include <stdio.h>
int main(int argc, char *argv[])
{
char escape = 0x1b;
printf("%c[43mthis is a test\nmore test%c[m\n", escape, escape);
printf("%c[7mreverse video%c[mback to normal\n", escape, escape);
}
The sequence is the escape character which is octal 033 or 0x1b, open
square bracket, a code suitable to the termial, and the letter m.
leaving out the number code resets back to normal output.
I think this is what you are looking for.
