If this is another attempt to get me to stare into a laser, I'm going to say "Fool me once."

The article is paywalled, but from the part I could read, it sounds like they're just making hyperbolic colors, which is a pretty well known phenomenon which you can experience at home: https://en.wikipedia.org/wiki/Impossible_color#Chimerical_colors

They've done it using a new technique which is cool, but seeing super saturated hyperbolic colors is not a new thing.

It's bright super-saturated teal. So now we know teal is "true" green.

This sounds cool to me. I’d love to see it.

Better be named "Octarine"

I will never have an original thought in my life.

Anyway, I'm on book 18 or so, 3rd pass, still finding jokes and references I missed. Calling it now, Discworld is the best fiction I've read in 40+ years.

Sir Pratchett was a genius. He will continue to be missed.

Also worth reading the books he co-wrote with Stephen Baxter.

Also worth reading the books he co-wrote with Stephen Baxter.

The first book is ok, but the rest of the series is pretty meh. Still bought and read them all as a Pratchett fan, but I wouldn't recommend them to others. If you want to expand past the Discworld series, Good Omens is a much better recommendation. Also Nation is a really good book too.

Similarly, I think I’ve read somewhere that pink isn’t in the color spectrum. Or was it magenta?

A lot of colors, like those, as well as gold, aren't on the spectrum of visible light either.

Gold is – it's an orangeish yellow. I think what you're meaning is that when people say "gold", they usually are referring to the material properties of the metal as well. But the actual color does have a spectral hue. Magenta on the other hand, (including shades of pink that fall under magenta) is not a spectral color, and is just how our brain interprets the combination of signals from our red and blue cones.

Right. If you took a picture of a piece of gold and either sampled a point or blurred it together to one color, it wouldn't look like gold any more.

I'm not quite sure what you mean. If you took a picture of an orange and sampled a pixel from it, it wouldn't look like an orange (fruit) any more, but it would look orange (color). Likewise sampling a pixel from a picture of a piece of gold wouldn't look like gold (metal), but it would still be gold (color).

It would just be yellow

Gold just looks like a dull yellow out of context.

I’ve always wondered why no one ever seems to mention that there’s no such thing as brown light.

BT_7274@lemmy.world · 5 pts · 1y (1 reply)

It’s orange. Brown is just really dark orange.

iopq@lemmy.world · 0 pts · 1y

It could be a very dark red or yellow as well

Pink is a shade of red, so pink itself is not a real color.
