This is a tangent, but I feel like we can't talk about LED christmas lights without linking to this video by tech connections: this video the tl;dw is that most color LED lights work by emitting a single frequency of light. Compared to classic christmas lights, which are incandescent filaments filtered through dyed glass, the LED lights look a bit... radioactive. My personal pet peeve are white LED lights. If you're not careful to buy the ones labeled "warm" they look cold, and imo, not very festive and inviting. Of course, this is all a matter of taste, but once I became privy to the difference, I could no longer ignore it. I guess I'm just a millennial nostalgic for the lights of my youth.
The blue is nicer if you do that. Technology Connections has made 3 videos over the last 5 years mostly centering around how he hates the blue led lights used in holiday lights. I think I've only seen the 2 yr old one, but now that I have I can't unsee it. The blue is just too blue. If you see a set that is all blue instead of multi-color it's unbearable. It's just too blue. White light in blue plastic is where it's at. this video [LINK] [LINK]
Technology Connections did some videos on "Making Holiday Lights Less Garish", where instead of using narrowband colored LEDs he filtered white ones: this video
