Hi Alexander, I'm a user of the site and I also purchased the book a few years ago and your course last month, I've been using the site much more often lately, learning about visitor pattern helped me a lot recently to solve several problems in a very elegant way, but tonight y eyes were not as sharp as the usual, and when I came to the site to check something, it wasn't pleasent to change from the dark themed IDE, colors are great in the site, i love orange too, but the brightness got me this night, I'd really apreciate and maybe i would be not the only one, thank you for the site and the effort you put in the structuring of the patterns, the work in them really notices when you navigate and read throgth the pages.

Sorry for the inconvenience. The dark theme is on my todo list. For now, you can use one of the browser extensions that work around this issue.
Thank you that worked perfectly so far.
