I'm sorry but I'm here to enjoy the amazing beauty nature has to offer, not explore a dank streamer room with stalactites. I understand they are trying to attract tourists, but does this really look better than just normal lights? If you're trying to show different layers, why did you pick the most ugly color combinations?
Let's put some cyan and magenta spot lights on El Capitan in Yosemite, that would be so cool! Kids will love it!
Think about if they used a simulated torch light. Used lighting that made the cave look like the way it was when our ancestors explored them. Or kept it dim and gave guests headlamps. Make it feel like we are exploring something humanity wasn't meant to see. Make it otherworldly. When you add RGB lights it feels like someone has already gone through here and violated the space for years. It feels grossly human instead of otherworldly
