I found this can be done by drawing a rectangle inside the progress bar  and to set its width according to the progress s current value  I also added support for right to left progress  This way you don t need to use the Image  and since Rectnalge Inflate isn t called the drawn rectangle is smaller   public partial class CFProgressBar   ProgressBar       public CFProgressBar                 InitializeComponent            this SetStyle ControlStyles UserPaint  true              protected override void OnPaintBackground PaintEventArgs pevent           protected override void OnPaint PaintEventArgs e                double scaleFactor      double Value -  double Minimum      double Maximum -  double Minimum            int currentWidth    int   double Width   scaleFactor           Rectangle rect          if  this RightToLeftLayout                        int currentX   Width - currentWidth              rect   new Rectangle currentX  0  this Width  this Height                     else             rect   new Rectangle 0  0  currentWidth  this Height            if  rect Width    0                        SolidBrush sBrush   new SolidBrush ForeColor               e Graphics FillRectangle sBrush  rect

OK  it took me a while to read all the answers and links  Here s what I got out of them   Sample Results  The accepted answer disables visual styles  it does allow you to set the color to anything you want  but the result looks plain     Using the following method  you can get something like this instead     How To  First  include this if you haven t  using System Runtime InteropServices   Second  you can either create this new class  or put its code into an existing static non-generic class   public static class ModifyProgressBarColor        DllImport  user32 dll   CharSet   CharSet Auto  SetLastError   false       static extern IntPtr SendMessage IntPtr hWnd  uint Msg  IntPtr w  IntPtr l       public static void SetState this ProgressBar pBar  int state                SendMessage pBar Handle  1040   IntPtr state  IntPtr Zero             Now  to use it  simply call   progressBar1 SetState 2    Note the second parameter in SetState  1   normal  green   2   error  red   3   warning  yellow    Hope it helps

Simply right click on your project in Visual Basic Solution Explorer  where your vb files are  and select properties from the menu  In the window that pops up deselect  Enable XP Visual Styles  and now when you set forecolor  it should work now

Quote   Usually the progress bar is either themed or honors the user s color preferences  So for changing the color you either need to turn off visual styles and set ForeColor or draw the control yourself   As for the continuous style instead of blocks you can set the Style property   pBar Style   ProgressBarStyle Continuous      ProgressBarStyle Continuous versus Blocks is useless with VistualStyles enabled     Block s  will only work with visual styles disabled      which renders all of this a moot point  with regards to custom progress color  With vistual styles disabled     the progress bar should be colored based on the forecolor   I used a combination of William Daniel s answer  with visual styles enabled  so the ForeColor will not just be flat with no style  and Barry s answer  to custom text on the progress bar  from  How do I put text on ProgressBar

EDIT  By the sounds of things you re using the XP Theme which has the green block based prog-bar  Try flipping your UI Style to Windows Classic and test again  but you may need to implement your own OnPaint event to get it to do what you want across all UI Styles  Or as someone else pointed out  disable the VisualStyles for your application   Original  As far as I know  the rendering of the Progress bar happens inline with the windows theme style that you ve chosen  win2K  xp  vista   You can change the color by setting the property  ProgressBar ForeColor   I m not sure that you can do much more however     does some googling  Theres an article here from MS KB on creating a  Smooth  progress bar   http   support microsoft com kb 323116

In the designer  you just need to set the ForeColor property to whatever color you d like   In the case of Red  there s a predefined color for it   To do it in code  C   do this   pgs ForeColor   Color Red    Edit  Oh yeah  also set the Style to continuous  In code  like this   pgs Style   System Windows Forms ProgressBarStyle Continuous    Another Edit  You ll also need to remove the line that reads Application EnableVisualStyles   from your Program cs  or similar    If you can t do this because you want the rest of the application to have visual styles  then I d suggest painting the control yourself or moving on to WPF since this kind of thing is easy with WPF  You can find a tutorial on owner drawing a progress bar on codeplex

Since the previous answers don t appear to work in with Visual Styles  You ll probably need to create your own class or extend the progress bar   public class NewProgressBar   ProgressBar       public NewProgressBar                 this SetStyle ControlStyles UserPaint  true              protected override void OnPaint PaintEventArgs e                Rectangle rec   e ClipRectangle           rec Width    int  rec Width     double Value   Maximum   - 4          if ProgressBarRenderer IsSupported             ProgressBarRenderer DrawHorizontalBar e Graphics  e ClipRectangle           rec Height   rec Height - 4          e Graphics FillRectangle Brushes Red  2  2  rec Width  rec Height             EDIT   Updated code to make the progress bar use the visual style for the background

I think that the simplest solutions of all  it s just a quick fix  but you can delete  comment the Application EnableVisualStyles   from Program cs  or however you have name your the part containing the Main function  After that you can freely change the color form the progress bar by progressBar ForeColor   Color TheColorYouDesire   static void Main                           Application EnableVisualStyles                Application SetCompatibleTextRenderingDefault false               Application Run new Form1
