Minecraft your Hue light will shine almost pure white matching the sun. Orange, and lightning wants flash white then fade to a darker blue. Travel to the final game The End, and your walls will light up with the ethereal purple glow from the horizon. Inside your cabin you'll get the flickering reds and yellows of the fireplace. In a nod to utility, it wants to flash red when you take damage.
It's a super-cool effect to watch in motion. Since it uses the APIs from Minecraft and Hue, it only works with those specific lights and single game. But as smarthome tech becomes cheaper and more prevalent, you can expect more. Github, then compile it and install it on a Minecraft server. See the link for full directions.
