St. Patrick’s Day Shamrocks for PowerPoint are ready to use clip-art style symbols that you can use within your presentation slides. Although the shamrock symbols you download from this page are green in color, they can be recolored using PowerPoint’s native options for fills, lines, and effects. These shamrock symbols are contained within a sample presentation you can download. Just copy the shamrock symbol you like and paste into another PowerPoint slide, or even a Word document or Excel worksheet. All these shamrock symbols are vector shapes, so you can easily edit them within your Microsoft Office program.
