How to Change Console Color in C++?

Last Updated : 05 Jun, 2024

In C++, most of the inbuilt input and output functions take input and show output from/to the console window. This can be useful for highlighting important information, creating visually appealing interfaces, or simply adding a touch of personalization to our console applications.

How to Change Console Color in C++?

By default, the console color is generally black text and white background but we can customize the appearance of our console output by changing the text and background colors using ANSI color codes.

ANSI escape codes are special character sequences that can be embedded within text to control formatting, including colors. While it is not supported on all platforms, ANSI escape codes offer some degree of portability.

Code	Color	Code	Color
30	Black	90	Bright Black
31	Red	91	Bright Red
32	Green	92	Bright Green
33	Yellow	93	Bright Yellow
34	Blue	94	Bright Blue
35	Magenta	95	Bright Magenta
36	Cyan	96	Bright Cyan
37	White	97	Bright White

Syntax of ANSI Color Codes

To use these codes in C++, you can use the \033 ANSI escape sequence followed by the code and m.

cout << "\033[32mThis is red text";

This change will be applied to all the text after this text. To reset is use [0m code.

C++ Program For Changing Console Color

C++

#include <iostream>
using namespace std;

// Function to set the console text color using ANSI escape
// codes
void SetColor(int textColor)
{
    cout << "\033[" << textColor << "m";
}

// Function to reset the console color
void ResetColor() { cout << "\033[0m"; }

int main()
{
    // Set text color to bright white (97) and background
    // color to blue (44)
    SetColor(31);
    cout
        << "This text is bright white on a blue background."
        << endl;

    // Reset to default colors
    ResetColor();
    cout << "This text is the default color." << endl;

    return 0;
}

Using Windows.h Functions (Windows-specific)

This approach provides direct access to console color manipulation functions on Windows systems. It offers a wider range of color options and customization possibilities.

Steps:

Include the <Windows.h> header
Get a handle to the console window.
Use SetConsoleTextAttribute function to change the console colors.

C++ Program to change console colors using Windows API:

C++

#include <iostream>
#include <windows.h>
using namespace std;

// Function to set the console text and background color
void SetColor(int textColor, int bgColor)
{
    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(hConsole,
                            (bgColor << 4) | textColor);
}

int main()
{
    // Set text color to white and background color to blue
    SetColor(15, 1);
    cout << "This text is white on a blue background."
         << endl;

    // Reset to default colors
    SetColor(7, 0);
    cout << "This text is the default color." << endl;

    return 0;
}
