google slide background image 2

Sometimes the default Google Slides themes feel a bit flat, so I dig around for a background image that adds texture without stealing attention from the text. A subtle gradient or a faint geometric pattern works best, especially if it matches the color palette of the presentation. I usually pick something that's high-res but not too busy, so the slides stay readable on a projector. It's a small tweak, but the right background can make the whole deck feel more polished.
