Red color website background quickly flashes when loading

When the website is loading on desktop or mobile, it will quickly flash the website's background to bright red before loading the content. Same with parallax scrolling, sometimes if the scrolling is slow it will show some red between sections.

I remember years ago I'd set the default site background to red, but it seems Squarespace has removed that style option. Any way to revert the site background to white or remove it altogether? 

Thank you! 

Can you share link to page where you have problem?

@tuanphan sorry about that, yes it's here: https://www.squareonepolitics.org/ 

@tuanphan Just checking in on the above to see if you have any advice -- thank you! 

Hi,

You try reduce top section image size. When the image takes time to load, it will display the body color behind.

I'm not sure if image reduction can solve the problem, if not then the only way is to change the red color to another color (if you need code to change color, you can let me know)

@tuanphan Thanks so much. If you could provide the code to change the color in this case, that would be much appreciated. Thank you.
