Example Algorithm for changing Color To Blue

image Processing

//my algorithm

            int width = image.Width;//need width of image
            int height = image.Height;//need height of image
            for (int x = 0; x < width; x++)
            {
            //getting pixel from width and height
                for (int y = 0; y <height; y++)
                {
                   
                    
                    //getting color of image
                    var c = image.GetPixel(x, y);
                   
                    double red = c.R / 10;
                    double green = c.G /5;
                    double blue = c.B *0.5;

                    image.SetPixel(x, y, Color.FromArgb((int)red, (int)green, (int)blue));


                }
               

            }
            pictureBox2.Image = image;

            return image;
