Question

How to change the color of the text in the console in C

Answer 1

#include <stdio.h>
#include <stdlib.h>

/*
Sets the default console foreground and background colors.

COLOR [attr]

  attr - Specifies color attribute of console output

Color attributes are specified by TWO hex digits -- the first
corresponds to the background; the second the foreground.  Each digit
can be any of the following values:

    0 = Black       8 = Gray
    1 = Blue        9 = Light Blue
    2 = Green       A = Light Green
    3 = Aqua        B = Light Aqua
    4 = Red         C = Light Red
    5 = Purple      D = Light Purple
    6 = Yellow      E = Light Yellow
    7 = White       F = Bright White

If no argument is given, this command restores the color to what it was
when CMD.EXE started.  This value either comes from the current console
window, the /T command line switch or from the DefaultColor registry
value.

The COLOR command sets ERRORLEVEL to 1 if an attempt is made to execute
the COLOR command with a foreground and background color that are the
same.

int main(void) {
	system("color A");
	puts("color A - Light Green");
}
     
 
      
/*
run:
       
color A - Light Green
  
*/
