What is the proper way to call multiple methods from a single event?

Question

I'm calling multiple color correction methods from a pictureBox click event. The problem is, sometimes a method will be skipped. Sometimes a method will run twice. So I may not be using the best possible way to call my methods. Code follows:

EDIT: I received a comment stating that the question is unclear. It seems clear to me. But in case I'm wrong, let me clarify: I am getting errors with my current way of calling multiple methods. What is the proper way to do so?

private void pictureBox1_Click(object sender, EventArgs e)
{
    pictureBox0.Image = pictureBox1.Image;                  

    foreach (PictureBox item in Controls.OfType<PictureBox>())
    {
        item.Image = pictureBox0.Image;
        item.Refresh(); 
    }

    runColorMethods();  
}      

private void runColorMethods()
{
    red();
    orange();
    yellow();
    green();
    blue();
    magenta(); 
}  

It would take too much space to show all six methods, one will suffice.

private void red()
{
    // declare initial variables 
    int xRed = 32;

    lock (lockObject)
    {
        // Get bitmap from picturebox
        Bitmap bmp1 = (Bitmap)pictureBox1.Image;

        // search through each pixel via x, y coordinates, examine and make changes. 
        // Dont let values exceed 255 or fall under 0.  
        for (int y = 0; y < bmp1.Height; y++)
            for (int x = 0; x < bmp1.Width; x++)
            {
                Color c = bmp1.GetPixel(x, y);
                int myRed = c.R, myGreen = c.G, myBlue = c.B;
                myRed += xRed;
                if (myRed > 255)
                    myRed = 255;
                bmp1.SetPixel(x, y, Color.FromArgb(255, myRed, myGreen, myBlue));
             }

        // assign the new bitmap to the picturebox
        pictureBox1.Image = (Bitmap)bmp1;
    } 

}

I've heard of multicast delegates being used to call multiple methods, but I do not know how to use them correctly, or if they are even the best way to go. Recommendations?
