String lights

While walking back to my dorm room the other day I passed someone's open door. The normal lights were off, and the only light was coming from the icicle string lights they had up as decoration. They gave off a warm golden glow, similar to the photo you see here.

This got me thinking about the fairly recent surge in LED usage, and how LEDs tend to look bluer than incandescent lights. As more and more people pick LEDs over incandescent lights, I'm curious to see how that will affect our perception of white light. Though incandescent lights may seem gently warm now and LEDs slightly too cold, in a few years I wouldn't be surprised if incandescent lights become unbearably yellow to us.
