// Configure Slide Master
SlideMaster slideMaster = presentation.SlideMasters[0];
slideMaster.Background = new CustomSlideBackground(new SolidFill(Color.FromArgb(194, 228, 249)));
        
// Add a new slide with content
presentation.Slides.Clear();
Slide slide1 = new Slide(slideMaster.Layouts.Get(SlideLayoutType.Title));
foreach (Shape shape in slide1.Shapes) {
    if (shape.Placeholder.Type is PlaceholderType.CenteredTitle) {
        TextArea textArea = new TextArea();
        TextParagraph paragraph = new TextParagraph();
        paragraph.Runs.Add(new TextRun { Text = "Daily Testing Status Report" });
        textArea.Paragraphs.Add(paragraph);
        shape.TextArea = textArea;
    }
    if (shape.Placeholder.Type is PlaceholderType.Subtitle) {
