Here is one of my favorite filters that I use. I've created it in Lightroom and saved it as one of my presets, which I usually apply to specific photos. One of those photos was taken during my short trip to London, where I had to sort out my visa for my travel to Ghana.
Having half a day, I decided to visit this unique yet iconic brutalist whole district called "The Barbican". It is in central London, and I must say that despite having been to London tens of times, I had never visited this area before. One thing I have to admit is that it's super ugly, yet beautifully harmonious - it's gray and depressing, yet some small flowers and green colors give so much hope, yet in my set, everything is pink. The whole place is amazing, and wandering around in that area makes it very exciting.
For a comparision here is different modern building on the other side of road just next to the Barbican
