Show HN: Ember – Redshift safe color palettes

"A warm filter is not a tinted overlay." That's lovely (I suppose), but only an AI would start a section by telling me what something is not, rather than what it is. It's also not really a calamari salad, but it didn't see fit to mention that. This time.

Strongest AI indicator: Words that may carry meaning, if you don't think so hard, but don't work towards any meaningful narrative (because there is none) -- they carry the LLMs need to generate text, not the reader's need to gain progressive understanding. All of this writing without a mind model of the reader shares the same flaws.

And it's an great question about relativistic redshift! That actually would end up with more or less the opposite result: you'd want to shift all of your palette colors and meaning into commanded-blue channels.

That's because the relativistic redshift pulls everything to longer wavelengths, so as you approached the speed of light, you'd start literally losing colors as they got red-shifted out of the human visual range.

The first thing you'd lose is the red channels (which would get shifted into the infrared, and thus be invisible). That happens at about 0.2c, depending on the wavelength of the red LEDs in your screen.

Then you lose green once you get to about 0.38c.

Blue doesn't disappear from your visible range until you get up to ~0.52c.

Faster than that, and the only things you'll be able to see with naked eye started off as ultraviolet frequencies (or above)! (aka - you'd need HW changes to your screen, so it's outside the realm of SW to fix)

Another thing I noticed is that most of the colors used there seem to be lower on the saturation side, with the exception of #8FF0FF. I'm assuming it's not by accident. Most people don't even think about colors in terms of saturation and value.
