Chicago's About to Get a Lot Less Orange
Same debate is going on in Rome at the moment, where orange-y light also contributes alot to the beauty of the city at night: <a href="https://www.nytimes.com/2017/03/27/world/europe/rome-streetlights-led-lights.html?_r=0" rel="nofollow">https://www.nytimes.com/2017/03/27/world/europe/rome-streetl...</a><p>What I wonder is: ok, so LED ligts save a lot of energy, which is great. But do they all have to be #FFFFFF white? Given that there's LEDs in all colours, would it be much more expensive to build/ buy/ run e.g. orange LEDs?
