Do you mean, by clicking the pixel with the mouse ? And does the form belong to the same application ? – digEmAll Feb 19 '12 at 21:24

Based on the code provided here,
I created an extension method that returns the color of a control pixel, given the client coordinates of the pixel:
public static class ControlExts
{
public static Color GetPixelColor(this Control c, int x, int y)
{
var screenCoords = c.PointToScreen(new Point(x, y));
return Win32.GetPixelColor(screenCoords.X, screenCoords.Y);
}
}
So, in your case you can do:
var desiredColor = myForm.GetPixelColor(10,10);
