I watched this one guy on youtube who knew a lot of commands and little building tricks when I was younger and he specifically had a video about how to make a rainbow gradient beacon wall which I thought was cool as hell so I'd spend multiple hours every single day building giant rainbow gradient beacon walls in superflat worlds. I ended up walling off an entire village with a rainbow beacon wall one time and made up lore about some sort of mysterious 'rainbow dragon' protector that would set up these giant walls of rainbows around villages to keep the villagers safe.
rainbow dragon...
