Homepage is empty

I can't for the life of me get anything to appear on the home page. I added a new page with some custom content and set the link to / but it's still blank.

For reference, I forked the blog template, changed some colors and started using it. I'm not sure if the homepage was blank before then because I hadn't uploaded any pages yet. Might be worth noting that the home page doesn't have the colors of the template either. The search page also doesn't have the right colors, but the archive page does.

Is there some sort of delay in between making posts / changing template and the homepage updating?
