Black 4.0
- justinclift 3y agoDoesn't seem to have a comparison vs Black 3.0?
- frob 3y agoIt's from a different article, but the author gave an interview to hackaday and gave a comparison there. https://hackaday.com/2023/10/31/black-4-0-is-the-new-ultrablack/ https://hackaday.com/2023/10/31/black-4-0-is-the-new-ultrabl... > “Black 4.0 absorbs an astonishing 99.95% of visible light which is about as close to full light absorption as you’ll ever get in a paint,” said Semple. He notes this outperforms Vantablack’s S-Vis spray on product which only achieves 99.8%, as did his previous Black 3.0 paint.
- justinclift 3y agoThanks, that's really helpful. :)
- wodenokoto 3y agoHow does it compare to vanta black?
- frob 3y agoIt's not in the posted link, but the author gave an interview to hackaday and addressed this. https://hackaday.com/2023/10/31/black-4-0-is-the-new-ultrablack/ https://hackaday.com/2023/10/31/black-4-0-is-the-new-ultrabl... > “Black 4.0 absorbs an astonishing 99.95% of visible light which is about as close to full light absorption as you’ll ever get in a paint,” said Semple. He notes this outperforms Vantablack’s S-Vis spray on product which only achieves 99.8%, as did his previous Black 3.0 paint. Also, you yourself can buy Black 3.0 and 4.0 whereas one person owns the worldwide artistic rights to Vantablack (who is also banned from buying Black X.0)
- mike_d 3y ago> one person owns the worldwide artistic rights to Vantablack Not that it really matters. The "artistic rights" were a one off marketing gimmick. You can't actually buy Vantablack as a paint. You have to have approval from the UK Ministry of Defense and then send your part to the Surrey Nanosystems facility to get coated.
- alephxyz 3y agoWouldn't want a bunch of ill-intentioned extremists to paint some asteroids with it and hurl them towards Earth.

- bloody-crow 3y agoThe site doesn't render properly in Firefox. Looks like an entirely white page with no content on it.
- kristianp 3y agoThat's ironic isn't it. Can I get this in a gloss?
- bartvk 3y agoIt renders fine for me. Latest macOS, latest FireFox. Do you have funky extensions installed?
- WithinReason 3y agoTry without extensions (private window)
- bayindirh 3y agoAnother Firefox user here. v119, Linux. Works fine.
- ciupicri 3y agoIt happened to me too when I refreshed the tab and also a couple of times when I tried to open it in a new tab.
- v3ss0n 3y agoi thought python formatter
- roydivision 3y agoPhew, I'm not alone
- golergka 3y agoImagine: a python formatter with an open source license that has a special clause to forbid usage by a programmer who have previously released a competing closed-source formatter.
- deleted 3y ago[deleted]
- tzmudzin 3y agoIt's rather: ... a competing formatter that may not be used on open-source projects. The composition of both paints is a trade secret ("closed-source formatters"). The controversy is about disallowing the use on a broad class of projects benefitting the society.
- masklinn 3y agoOr rather a competing formatter that may only be used in one single individual's projects.
- shpx 3y agoIt wouldn't be an open source license then.
- tmtvl 3y agoI thought (though didn't really expect) the reflective programming language Black (<https://github.com/readevalprintlove/black https://github.com/readevalprintlove/black>).
- SirMaster 3y agoI hope it’s a lot darker than Black 3.0. Black 3.0 was severely disappointing and way less black than simple triple black velvet material in my home theater.
- asah 3y agoI was also disappointed in 3.0 vs 2.0 Also, while I lived 2.0 is important to dust objects otherwise the dust will ruin the effect. Here's a ledge before painting: https://photos.app.goo.gl/9gxk4d3NqcUrt3Bj6 https://photos.app.goo.gl/9gxk4d3NqcUrt3Bj6 Note the distracting lines. Here's with b2.0 painted in the groove, notice how it's gone! https://photos.app.goo.gl/rKNrnffQmkCGAxXBA https://photos.app.goo.gl/rKNrnffQmkCGAxXBA Closeup https://photos.app.goo.gl/rAUGZmjGxtV1gW22A https://photos.app.goo.gl/rAUGZmjGxtV1gW22A
- Cthulhu_ 3y agoVelvet being the operative word; its surface texture captures light, like vantablack creating a furry surface. It's a challenge with paint because it's applied in a flat layer (usually).
- SirMaster 3y agoRight. But Black 3.0 claims 99.6% light absorption. So if Black 3.0 next to black velvet looks like this? What must be the light absorption value of black velvet? https://cdn.discordapp.com/attachments/824109424255434803/887758603958779935/image1.jpg https://cdn.discordapp.com/attachments/824109424255434803/88... Black 4.0 now apparently claims 99.95? So yeah, I wonder how it now compares.

- Nezteb 3y agoThis should be the top comment of the thread. I wouldn’t have had any idea what was going on otherwise.
- ale42 3y agoIt is a the top, at least now on my PC ;-)
- Jugurtha 3y agoThis is so funny. >Artists like Christian Furr and Stuart Semple have criticised Kapoor for what they view to be the appropriation of a unique material to the exclusion of others.[69][70] In retaliation, Semple developed a pigment called the "pinkest pink" and specifically made it available to everyone except Anish Kapoor and anyone affiliated with him.[71][72] He later stated that the move was itself intended as something like performance art and that he did not anticipate the amount of attention it received.[67] In December 2016, Kapoor obtained the pigment and posted an image on Instagram of his extended middle finger which had been dipped in Semple's pink.[73] Semple also developed more products such as "Black 2.0" and "Black 3.0", which are supposed to look nearly identical to Vantablack despite being acrylic, and "Diamond Dust", an extremely reflective glitter made of crushed glass shards that are designed to hurt Kapoor if he dipped his finger in it
- roydivision 3y agoOblig quote: "It’s like, how much more black could this be? And the answer is none. None more black."
- TheCleric 3y agoWell, until Black 5.0

- hellotheretoday 3y agoI got to see a ball painted with vantablack in real life. It was surreal, it looked almost flat when you glanced at it but then you realized it had depth if you looked more closely. I wasn’t allowed to touch it, the man with gloves was very serious about that. I really wanted to touch it. I bet it would’ve been weird to feel it as you looked at it. This is apparently more black than vantablack. I have no need for this but I kind of want to buy some to paint a ball and finally see what it’s like
- kelsolaar 3y agoWithout a reflectance/absorptance value it is hard to say but Black 3.0 with 99.6% is nowhere near close to Vantablack with 99.965%. Edit: People are quoting 99.95% for Black 4.0 which is impressive!
- mi_lk 3y ago> Black 3.0 with 99.6% is nowhere near close to Vantablack with 99.965% Curious, under what circumstances will this 0.365% be practically important?
- isilofi 3y agoHuman vision is logscale, not linear. So in a comparison, you will see a difference.
- tubs 3y agoConsider it in terms of error. The difference is 0.4 to 0.035 An order of magnitude more light reflected.
- sandworm101 3y agoInvert those numbers. 99.6 is actually about 10x brighter, more reflective, than 99.965. Depending on light levels, this would be very noticeable.
- dr_kiszonka 3y ago
- 112233 3y agoThis looks impressive. Maybe someone will know: Would painting an inside of a old manual camera lens barrel with this cause issues? Like, dust, fungus, I don't know. Because there are a couple of vintage lenses that could use a bit more contrast.
- buro9 3y agoInteresting, his pinkiest pink still looks to be quite raspberry (red), he should try a pantone 2037 as it's a purer pink that isn't as darkened by red tone.
- qwertox 3y agoIt comes with a disclaimer, though: > *disclaimer: we're not actually sure if this is the worlds pinkest pink ever, it could well be! It's the pinkest we could come up with, and we've not seen anything pinker. The "Gossip" "hot pink" looks like the pantone pink you mention.
- omnicognate 3y agoHow do you measure how "pink" something is and whether one thing is more "pink" than another? For black it's just albedo.
- dist-epoch 3y agoPink is not a well defined color, especially when considering it's actually a mix of red and blue.
- thejohnconway 3y agoPink can have blue in it, of course, but its defining feature is a light tint of red. With paint you mix red and white.
- hoseja 3y agoAre you looking at the paintng or using a RGB monitor?
- Doxin 3y agoOwning a small tub of the stuff, once used as a paint it's actually startlingly pink. Most definitely more pink than anything else I've ever seen. I would not describe it as reddish at all.
- SamuelAdams 3y agoThey ought to add a white paint product line and make it the whitest paint ever. Paint the roofs of California with it so it reflects sunlight and reduces energy costs.
- 22c 3y agoTech Ingredients has an interesting YouTube video about this. https://www.youtube.com/watch?v=5zW9_ztTiw8 https://www.youtube.com/watch?v=5zW9_ztTiw8
- traviswt 3y agoThey were one step further than just reflecting heat, they were tuning emissivity to actually give off heat and cool the surface underneath. Extremely impressive from a heat transfer perspective to cool a surface passively! The idea is basically "sky is really cold, give it your heat." Fascinating.

- aitchnyu 3y agoMy sedan has reflections from the dash on the windshield and it gets annoying in the sun. Can this paint help or will it turn into millions of lung impaling particles when the car is parked in the sun?
- throwaway290 3y agoProbably not much more than your car's interior plastics already provide
- _Parfait_ 3y agoYou want to use acrylic paint to solve this issue?
- lbotos 3y agohttp://speed.academy/flocking-dash-flock-how-to-steps-diy/ http://speed.academy/flocking-dash-flock-how-to-steps-diy/ Race cars solve this with flocking. I’m sure someone makes a “flocking mat” or something you can rest in the dash
- autoexec 3y agoI'll save folks a click: flocking = painting your dash matte black
- lbotos 3y agoNo, it's actually not a paint, it's more like a velvet: "Flocking is the application of millions of tiny fibers onto an adhesive-coated surface to create a velvet-like texture." https://www.flockit.com/what-is-flocking/whatisflocking https://www.flockit.com/what-is-flocking/whatisflocking
- amluto 3y agoTry polarized sunglasses. At typical windshield angles, the reflection from the dash to your eyes is close enough to Brewster’s angle for the reflection to be highly polarized.
- NelsonMinar 3y agoIt is as black as Malevich's Square The cold furnace in which we stare A high pitch on a future scale It is a starless winternight's tale It suits you well It is that black, It is that black It is that black, It is that black
- edouard-harris 3y agoIf Steve Jobs had sold paint.
- divbzero 3y ago“Absorbs all the light in the universe as well as other universes.” I wonder how much of the electromagnetic spectrum it actually absorbs. Surely it’s not the entire spectrum, but does the absorption band stretch beyond visible light?
