Where is this glow coming from?

This is probably going to be something simple but I’ve been searching for hours, I have this site I’m building (https://doctopus-staging.webflow.io/)

I used a template and I can’t for the life of me figure out how to change the color of the purple glow under the screenshot of my platform.

Any help?

Hey Christian, you’ll need to share your designer readonly link.
