Made a tiny color lib: nutelch 🌰 It sits between OKLCh and OkHSL. You dial chroma as a fraction of the way to the gamut cusp (so "saturation" means the same thing at every L & H, never out of gamut), but the result is still a plain oklch()...

Eric Rohmer on the use of Colour in "La Collectionneuse" (1967) and "Claire's Knee" (1970): "I didn't use color as a dramatic element, as some filmmakers have done. For me it's something inherent in the film as a whole. I think that in 'La Collectionneuse' (1967) color above all heightens the sense of reality and increases the immediacy of the settings. In this film color acts in an indirect way; it's not direct and there aren't any color effects, as there are for example in Bergman's most recent film, his second one in color, where the color is very deliberately worked out and he gets his effects mainly by the way he uses red. I've never tried for dramatic effects of this kind, but. for example, the sense of time-evening, morning, and so on-can be rendered in a much more precise way through color. Color can also give a stronger sense of warmth, of heat, for when the film is in black-and-white you get less of a feeling of the different moments of the day, and there is less of what you might call a tactile impression about it. In 'Claire's Knee' (1970), I think it works in the same way: the presence of the lake and the mountains is stronger in color than in black-and-white. It's a film I couldn't imagine in black-and-white. The color green seems to me essential in that film, I couldn't imagine it without the green in it. And the blue too-the cold color as a whole. This film mould have no value for me in black-and-white. It's a very difficult thing to explain. It's more a feeling I have that can't be reasoned out logically." (Eric Rohmer's interview with Graham Petrie, Film Quarterly, 1971)

🇳🇱 AMSTERDAM SCIENTISTS CREATE “CHAMELEON SKIN” THAT CHANGES COLOR WITHOUT PIGMENT Scientists at the University of Amsterdam have developed a new nanomaterial that changes color like a chameleon, using no pigment, no paint, and no electricity. It is made from an extremely thin layer of silicon, about one thousandth the width of a human hair. The surface is cut with patterns so small they are invisible to the eye, inspired by the Japanese art of kirigami, which uses cuts and folds to make flexible designs. When the material stretches, those tiny shapes twist and tilt, changing how light bounces off the surface. The color shift comes from light interference, not chemical dyes. As the spacing between the nanostructures changes, different wavelengths of light cancel or reinforce each other, creating visible color shifts. The same natural physics explains why soap bubbles shimmer with rainbow patterns or why butterfly wings flash blue and green. Lead researcher Davide Ruzzene explained, “By nanopatterning the thin silicon membrane, we made it act as both a mechanical metamaterial and an optical metasurface, letting structure, not pigment, control color.” In simpler terms, the material physically moves and optically transforms at the same time. Because it does not rely on power or fading dyes, it could be used in military camouflage that changes color in motion, medical bandages that show strain or swelling, or flexible displays that never need charging. This is not science fiction but real nanoscience, turning light and motion into a living display. Source: Eugene, PhysOrg

Elon Musk measures every civilization by a single number. By that number, we have not begun. Not by armies. Not by gold. By energy. By how much of it you can actually hold. A Russian physicist named Kardashev drew the scale in the sixties. The first rung should be easy. Musk: “If you’re Type I, you’re using most the energy of your planet.” That is not greatness. That is the entry fee. The moment a species stops being primitive. We have not paid it. Musk: “We’re still using a tiny fraction of the sun’s energy that reaches our planet.” And what reaches us is already almost nothing. Musk: “The Earth only receives about half a billionth of the sun’s energy.” Half a billionth. That is the entire inheritance of everyone who has ever lived. And we built everything we know on the fraction we bothered to catch. Musk: “The sun is 99.8 percent of all mass in the solar system.” Everything you have ever called the world is the rounding error. Every empire, every fortune, every border rose and fell inside a fraction of a fraction. Every war was fought over scraps. Beneath a furnace pouring out more in a single second than we will burn in a hundred years. Every economy ever designed assumed there was not enough. The sun disproved that assumption every morning since the Earth was formed. The abundance was never missing. It fell on us the whole time. We kept our eyes on the dirt. So the scale stops being a measurement. It becomes a verdict. It does not ask how advanced you are. It asks how much smallness you agreed to. Musk looked at the same sky as everyone else. And refused to sign. Scarcity was never handed to us. The sun never rationed anything. We did.
