How do I create gradients with transparency in Google Slides?

Filling shapes with transparency gradients in Google Slides is a way to create beautiful overlay effects.

First, select the shape you want to edit, then click on the Fill color icon on the toolbar.
This opens up the color palette. In the Gradient tab, select the option
Custom at the very bottom. The Custom Gradient settings panel will now open.
Select a Gradient Stop and click on the color circle. Then choose the Custom option. You’ll be taken to the color picker panel. Here, you can choose any color you want and also adjust its transparency.
Then repeat the same steps for the other Gradient Stop. When you’re done selecting your colors, click OK.

Use transparent gradients in several overlapped shapes to achieve a beautiful effect.
