Which is why I was always baffled by the decorative lights in my old office.
It was a wall with small scattered lights in different colors, so they used recessed LEDs. Fine. But instead of color LEDs with a neutral diffuser, it had red+green+blue triple LEDs to make white light, with a red/green/blue plastic in front to recolor it!
I understand how this could be cheaper to assemble or maintain, but I'll never not balk at a system that has components undoing each other's work. Feels almost disrepectful to the technology.
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.
Something odd about that ultra-blue color - when I'm outside at night, I can see any lit up sign in relatively good focus with my glasses on. Green signs, red signs, etc.
But anything blue always looks blurry unless I'm very close to it.
The lenses in your eyes refract different wavelengths at different angles - think of a rainbow coming out of a prism. Only one wavelength can be perfectly tuned to project a clear image onto your retinas. We are optimized for green, red is close enough, but blue always looks blurry.
But the commenter said it was red, green, and blue LEDs together, with a blue diffuser over them. Depending on the diffuser, that could produce a more pleasant result (by allowing some monochromatic red and green through), but it presumably wouldn't solve the underlying problem that monochromatic blue light can be unpleasant.
Are you sure they were RGB triplets and not white LEDs? Either way, is fun to imagine continuing this - grouping three of these filtered LED lights to make a new white light source, which you can then again filter with translucent plastic, etc!
Imagine, if you built a giant grid of such things, and could modulate the tranlucency 30 times a second or so, you could show some sort of.... moving picture show.
