For example I have Philips Hue lights behind the TV/Screen on my living room wall, and I use their "color loop" behind the screen when watching movies etc. The problem is that "TV", "Television" and "Screen" are semi-protected words, so "turn off tv lights" ends up with the TV being turned off 9/10 times. "We" compromised and those lights are now called "screen wall" lights
As for setting certain lights to "the color loop", what used to be a 90% success rate (the other 10% turning my lights to "the color blue/bloo(p)") will now set the lights of the room I'm currently in to the color loop, which is usually the living room, not the screen wall. Also as recently as this summer I used to be able to set the whole house to "the color loop" this feature recently disappeared. The color loop slowly and nearly imperceptibly fades the colors from red to green to blue etc over several minutes. It's technically part of "hue labs" but it's a "beta feature" that's been available in the product now for over three years so I would argue it is core functionality at this point.
