this is entirely the result in a shift in marketing. back in the day, people would wander around outside and look at things, so stores and restaurants had to be these big attention grabbing advertisements for themselves, people would literally only find them by spotting the colorful bullshit and being interested because people existed within the world. that meant crazy 3d billboards, giant animals on your McDonald's, bright colors everywhere. the point of change was Yelp, Google reviews, social media presence - all the colorful superstimulus moved into the internet, in crazy short form video commercials and colorful images - they didn't need to spend money on all that in person any more because no one was finding them like that any more, they began to find everything online. just think about it, when you want to go to a restaurant, you don't drive around and look at options, that's what people used to do! now you go online, where all the missing superstimulus colors are! they abandoned spending extra money on the locations because it was no longer accomplishing the thing it was always there for: marketing.
