When you make the width of your Minecraft screen really wide and stand next to lava (make lava flow from a pillar, make sure lava is 1x1, and into a hole. Place a block next to it, stand next to block, facing toward lava, and look down), your screen will turn orange even if you aren't in the lava.

And for some reason immediately I took the screenshots my game crashed lol
