c++ shell backgroudn color code example

Example 1: c++ console color some digits

#include "colormod.h" // namespace Color
#include <iostream>
using namespace std;
int main() {
    Color::Modifier red(Color::FG_RED);
    Color::Modifier def(Color::FG_DEFAULT);
    cout << "This ->" << red << "word" << def << "<- is red." << endl;
}

#include <ostream>
namespace Color {
    enum Code {
        FG_RED      = 31,
        FG_GREEN    = 32,
        FG_BLUE     = 34,
        FG_DEFAULT  = 39,
        BG_RED      = 41,
        BG_GREEN    = 42,
        BG_BLUE     = 44,
        BG_DEFAULT  = 49
    };
    class Modifier {
        Code code;
    public:
        Modifier(Code pCode) : code(pCode) {}
        friend std::ostream&
        operator<<(std::ostream& os, const Modifier& mod) {
            return os << "\033[" << mod.code << "m";
        }
    };
}

Example 2: cout color

#define RESET   "\033[0m"
#define BLACK   "\033[30m"      /* Black */
#define RED     "\033[31m"      /* Red */
#define GREEN   "\033[32m"      /* Green */
#define YELLOW  "\033[33m"      /* Yellow */
#define BLUE    "\033[34m"      /* Blue */
#define MAGENTA "\033[35m"      /* Magenta */
#define CYAN    "\033[36m"      /* Cyan */
#define WHITE   "\033[37m"      /* White */
#define BOLDBLACK   "\033[1m\033[30m"      /* Bold Black */
