Shape fills such as solid colors, gradients, pictures, and textures can have a Transparency attribute that lets you reduce the opacity of a fill so that the slide object or background behind shows through.
Transparency is calculated in percentages and you can change its value all the way from 0 to 100%. Some fill options, such as pattern and slide background have no option to change Transparency. Look at Figure 1 below, and you will see the original shapes on the left with their semi-transparent counterparts on the right. We intentionally placed all these shapes on a patterned background so that you can see the pattern through the semi-transparent shapes on the right.

To learn to set a Transparency value for your shape in PowerPoint 2016 for Mac, follow these steps:
- Select the shape that has a solid color, gradient, pictures or texture fill. Right-click (or Ctrl + click) the shape to bring up the contextual menu that you can see in Figure 2. Within this menu, choose the Format Shape option.
Figure 2: Format Shape option selected
- This brings up the Format Shape Task Pane that you see in Figure 3. Options may differ depending upon the original fill of your selected shape. In this instance, our shape had a solid fill. You drag the Transparency slider, highlighted in red within Figure 3 to change the Transparency value.

- The Transparency slider for Picture or texture fill is similarly highlighted in red within Figure 4, below.

- Gradient fills work a little differently as far as Transparency is concerned. You need to adjust the transparency value of every single color Stop comprised within the gradient fill you choose. To do that, select each Stop of your gradient individually, and change its Transparency, as shown highlighted in red within Figure 5, below.

- Set the Transparency value as required. In Figure 6 you can see the Fill Transparency of the shape that we selected earlier, set to 50%.
