Hi Samony Me In C# the default ProgressBar control does not provide a direct property to change its color. However you can achieve this by overriding the OnPaint method or using a custom control. Below is a simple approach using the ProgressBar control with a custom drawing technique. First you need to create a subclass of ProgressBar and override the OnPaint method to customize the appearance: using System; using System.Drawing; using System.Windows.Forms; public class CustomProgressBar : ProgressBar { protected override void OnPaint(PaintEventArgs e) { // Draw the background e.Graphics.FillRectangle(Brushes.LightGray this.ClientRectangle); // Draw the progress float percentage = (float)this.Value / this.Maximum; e.Graphics.FillRectangle(Brushes.Green 0 0 this.Width * percentage this.Height); } } Then replace your existing ProgressBar in the form with CustomProgressBar . You can change the color by modifying the Brushes.Green to any color you prefer. This way you can dynamically change the color of the progress bar without creating a new instance. To use it simply instantiate CustomProgressBar in your form and set its properties as needed.

You can change the color of an existing progress bar on a form by setting its ForeColor property in the code. Here's an example in C#: progressBar1.ForeColor = Color.Red; // Change to any color you want This will change the progress bar's color without creating a new one. Just make sure the color you set is compatible with the background color of the progress bar for good visibility.
