Blue and green theme and related symbolism in train station ads

http://www.matthaydenblog.com/2022/07/in-blue-and-green-neighbours-exits.html There were two very different ads that seemed to feature this blue and green theme that I keep seeing lately. They were followed by one for cruise liner P and O that included classic one eye symbolism (blink and you'll miss it!) as well as the drinking of red liquid and blue and white deck chairs.
