In a long-long-time-ago part of my life, I emerged one day from a bunker underground to discover that there was a roiling windstorm of fine, orange sand. In every direction, city buildings peeked out of the apocalypse orange fog, palm tree leaves stretched horizontally and snapping in the wind. I had spent all day indoors, under 60Hz fluorescent lighting. I stood just outside the vestibule of the building, looking around at the scene. Every fluorescent light, normally white, was intensely blue—my eyes attempting to normalize the unusually orange scene by adding a fuckton of blue to everything, making the cooler lights even bluer.
This was super-trippy to me, and the first time I looked away from a f.lux'ed screen, I was intensely reminded of the experience. And that's pretty much the barrier between me and f.lux. I like the science. But it totally fucks with me.
