Sharp, overly bright, piercing colors. I get that they were designed to be a wavelength that could be used for tv screens, but as christmas lights the colors are too primary. Like the colors of legos. They give off an eerie glow like a television that's the only source of light in the room.
The incandescent Christmas bulbs that were made before LEDs tried to achieve these colors but the painted glass naturally filtered them into more passive hues. The blue has a touch of teal. The red has a tough of pink. The orange is amber. And so on. I'm trying to recreate those colors as well as the traditional differences in brightness. As well as new colors.
