Complex Template - Need Design Help

It’s been almost 2 years since I last used Webflow and I wish I didn’t drop the ball…

I’m using an old template for a new business website but I’m having issues updating the background color. Now I’m no dummy, I know how to do it but for some reason when I update the color there’s no change because I’m finding hard to navigate where I need to do it.

See the website link below to read through the design structure.

Also is there a way to change the font outline color?
