Theme Colors Looks Different on Mobile vs Computer (origin)

Hi! I recently was helped with updating my origin theme background to be all white for my collections/product pages. However when I go to view my product pages as a consumer on my mobile device, all of my colors are reverted back to the original color of the Origin theme. It appears white on my computer though. Can someone please help with this? Its extremely frustrating

Thanks so much for reaching out! Yes please, any help would be greatly
appreciated. I really just want an all white background for my collection
and product pages.
