HTML color codes, also known as hex color codes, are widely used in web development to define colors in a web page. Although primarily used in web design, these color codes can also be useful in various Windows applications, especially when customizing user interfaces or creating scripts that involve color output.

In this article, we will explore how to use HTML color codes in different Windows environments, including PowerShell scripts and batch files. We will provide practical examples to help you understand how to apply these codes effectively.

Examples:

1. Using HTML Color Codes in PowerShell

PowerShell allows you to customize the console output using different colors. You can use HTML color codes to set the foreground and background colors for your text.

Example: PowerShell Script to Display Colored Text

# Function to convert HTML hex color code to RGB
function Convert-HexToRGB {
    param (
        [string]$hexColor
    )
    $r = [Convert]::ToInt32($hexColor.Substring(1, 2), 16)
    $g = [Convert]::ToInt32($hexColor.Substring(3, 2), 16)
    $b = [Convert]::ToInt32($hexColor.Substring(5, 2), 16)
    return [PSCustomObject]@{R=$r; G=$g; B=$b}
}

# Function to set console text color
function Set-ConsoleColor {
    param (
        [string]$foregroundColor,
        [string]$backgroundColor
    )
    $fgRGB = Convert-HexToRGB -hexColor $foregroundColor
    $bgRGB = Convert-HexToRGB -hexColor $backgroundColor

    $host.UI.RawUI.ForegroundColor = [System.ConsoleColor]::FromArgb($fgRGB.R, $fgRGB.G, $fgRGB.B)
    $host.UI.RawUI.BackgroundColor = [System.ConsoleColor]::FromArgb($bgRGB.R, $bgRGB.G, $bgRGB.B)
}

# Example usage
Set-ConsoleColor -foregroundColor "#FF5733" -backgroundColor "#333333"
Write-Host "This is a test message with custom colors"

2. Using HTML Color Codes in Batch Files

Batch files do not natively support HTML color codes, but you can use ANSI escape codes to change the text color in the Command Prompt.

Example: Batch File to Display Colored Text

@echo off
:: Enable ANSI escape sequences
for /F "tokens=2 delims==" %%i in ('"prompt $E"^|cmd') do set "ESC=%%i"

:: Set text color (foreground: red, background: black)
echo %ESC%[31;40mThis is a test message with custom colors%ESC%[0m

3. Using HTML Color Codes in Windows Forms Applications

If you are developing a Windows Forms application using C#, you can use HTML color codes to set the colors of various UI elements.

Example: C# Code to Set Background Color Using HTML Color Code

using System;
using System.Drawing;
using System.Windows.Forms;

public class MainForm : Form
{
    public MainForm()
    {
        this.Text = "HTML Color Code Example";
        this.Size = new Size(300, 200);

        // Convert HTML color code to Color object
        Color backgroundColor = ColorTranslator.FromHtml("#FF5733");

        // Set form background color
        this.BackColor = backgroundColor;
    }

    [STAThread]
    public static void Main()
    {
        Application.EnableVisualStyles();
        Application.Run(new MainForm());
    }
}

Conclusion

While HTML color codes are primarily used in web development, they can also be applied in various Windows environments to customize the appearance of scripts and applications. By converting HTML color codes to RGB values, you can use them in PowerShell scripts, batch files, and Windows Forms applications.
