    There's no way in standard C++.

    In Windows, there's a few API functions you can use for that. If forgot what they are.

    In *nix consoles, you do it by writing the special escape sequences to the console that are interpreted as commands to change colour or similar properties. Look for ANSI escape sequences.

    Curses defines its own functions for controlling colour.

    You need to find the function and delcare it in the source code.

    Code:
    void DrawColorString(string szText, int X, int Y, WORD color)
    {
       HANDLE OutputH;
      COORD position = {X, Y};
      OutputH = GetStdHandle(STD_OUTPUT_HANDLE);
      SetConsoleTextAttribute(OutputH, color);
      SetConsoleCursorPosition(OutputH, position);
      cout << szText;
    }
    This works with:

    Code:
    DrawColorString("",0,5,FOREGROUND_RED);

    Or you can use...

    Code:
    system ( "color 0C" );
    ...with the corresponding digit values:

    Code:
    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
