alt Hacker NewsIt is very interesting that whereas an incandescent lightbulb and a white LED (e.g., that Macbook screen) appear to us the same colour, their underlying spectra are very different (a solid black body radiation spectrum from the former and a choppy one from the latter).
I vaguely recall this is also known to cause a phenomenon where certain material can appear a false colour under certain light (especially a problem in case of, say, physical paintings and their various pigments), if whatever bands it reflects would align with the spectrum of emitted light in an unfortunate way.

I miss the low-pressure sodium street lights that used to be ubiquitous in Britain. The light was virtually monochromatic, which created a very specific aesthetic at night. Modern white LEDs feel more like a bad approximation of day rather than embracing the idea night should look different I think.
LEDs are much more flexible with colour anyway, we should have tried to keep some visual continuity rather than going straight for the harsh high-K white in my opinion.
