Is the PPT template for graduation thesis defense best dark?

Hello, I finished my thesis defense a few days ago. I don't have any special requirements for the color and font of PPT template, as long as it is fresh, which means that people don't feel heavy after reading it, mainly refreshing. The PPT system comes with several templates. I chose lotus at that time, with a lighter background and a darker font.

However, it should be noted that if you choose a dark template, you must choose a brighter font color, so that it will not look too laborious on the projection cloth. In other words, the background color and font color are darker and lighter.

I hope what I said can help you, and I wish you a happy graduation!
