Answer 1

From the mouse click event argument e, you can get the Point with the exact co-ordinates of the click:

Point clickPoint = e.GetPosition(backgroundControlWithImg);

Then get the colour of the image at that position using something like:

System.Drawing.Image image = backgroundControl.BackgroundImage;
Bitmap _bitmap = new Bitmap(image);
Color _color = bitmap.GetPixel(Point.x, Point.y);

Something like that. What are you using for the Color Picker, WPF or?
