Deuteranopia is a type of red-green color blindness characterized by the inability to distinguish red and green pigments. Protanopia is another type of red-green color deficiency. Both are primarily caused by recessive genes in the X chromosome -(link)
More unusual is total colour blindness, achromatapsia - link. I shared a chemistry lab bench with a lad who was completely colour blind, which meant I ended up telling him the point of change whenever we were titrating using a coloured indicator. He and his brothers all had the same condition and were studied extensively. It was fascinating asking him what he saw because he couldn't describe it at all.
It won't just be him who can't describe it. With the exception of a statement as to the wavelength of the light of that colour, I defy anyone to come up with a description of a colour (say 'red') which doesn't amount to 'red is the colour of <fire or an apple or some other red thing>'. Otherwise, we're in the same world as when we talk about the ultraviolet or the infrared or radio waves or any other electromagnetic radiation that the nerves in our eyes don't pick up.
I wouldn't expect someone to be be seeing what I think of as red and calling it blue.
I think this is because - in practice if not in principle - we learn colours by being shown things of that colour: 'look at that red fire engine' leads an individual to believe that the colour that they perceive the fire engine to be is known as 'red'. But that doesn't mean that the colour that they perceive is the same as the colour that anyone else perceives. I've heard an anecdote of someone seeing a (ginger?) cat and exclaiming 'what a lovely green cat!' - because on the basis of their colour perception, the cat was the same perceived colour as grass, and they'd been told that grass was green.
That sounds to me exactly like the most common kind of colour blindness - red/green, which is a different kind of thing - colours that look different to each other to people with normal colour vision looking the same to colour-blind individuals. My eldest has the this and to him everything from red to green (via ginger cats) looks much the same. Before he was diagnosed we wondered why he loved blue so much. It's not surprising when everything else looks orangey brown.
Thank you for supplying a couple of words which had dropped out of my use in the 1980s. I knew that they were there, but had to work round titration and indicator. (Actually, I don't think titration was involved, as my mental replay doesn't have the kit for that. But I used up all the indicator - I had assumed that spring waters from the Chalk and from the Greensand would have different pH.)
A reminder that Trump corrupts everyone and everything he comes in contact with, his post-election legal team ("the Kraken") seem to be having a very bad day in court today. The context is that they're being subjected to a disciplinary hearing for filing suits in bad faith with "facts" the attorneys allegedly knew at the time of trial to be false.
For those who want a more freewheeling discussion of the hearing not constrained by Reuters' stylebook, there's this Twitter thread. A sample:
Judge Linda Parker tried to cut off Howard Kleinhendler, one of the Kraken lawyers, and he said to her: "just one second." She did *not* like that. "I'm moving on," she said to him.
He was trying to explain that a formatting error led to the complaint being almost unreadable.
ETA: it's easy to imagine an experiment where people are shown monochromatic and composite light, and ask to say which composite light is "the same colour as" the monochromatic one. And I think that has to expose differences in chromatic sensitivity between people. I don't know if it's been done, though - I suspect it has.
Some time with Mr. Google reveals that this sort of thing has indeed been done - in this Nature article, for example. The procedure consisted of alternating a "standard yellow light" with a blend of red and green, and adjusting the blend until the viewer thought the colour matched the yellow. Among other things, this paper reports a systematic difference between male and female colour perception in people with "normal" colour vision.
You mean like light in the ~480nm wavelength range? As opposed to a subjective and variable perception of colour based on the wavelengths of light reflected by an object filtered through the eyes and interpreted differently by each brain?
There would be nothing special about ~480nm if it weren't that people's subjective and variable perception of colour largely agrees in finding electromagnetic radiation of that wavelength a clear case of blue. The significance of that particular number derives from the significance of blue in human life rather than the other way around.
I've also seen TANGERINE, which is a colour you can't satisfactorily produce with a single wavelength of light, and brings us back to the ex-president in question.

I read somewhere that one of the lawyers broke down in Court, but not Powell or the other leaders. I don't know how junior the lawyers assisting were, but it used to be common for very young lawyers in corporate firms to do the grunt work while the seniors set direction and gave final approval. It takes a strong-minded person to make an ethical stand before they have found their feet in a profession. I don't think I could do it. I'd be sobbing at the bar table too.
She's also going with "I'm not crying, you're crying":
“Kraken” lawyer Julia Haller is adamant that she didn’t actually cry during a sanctions hearing in Michigan on Monday, but there were times as her voice quavered and cracked that she sounded close.
On Haller's background:
Haller's LinkedIn profile says she's a "litigator with over twenty years of experience in case strategy, complex matters, trials and administrative proceedings." Currently in private practice, she did stints during the Trump administration at the Department of Homeland Security, the Department of Housing and Urban Development and the White House.

I don't think it matters whether she's crying or not. I do think it matters that her answer to everything but EVERYTHING was, "just give us an evidentiary hearing and we promise we'll make complete sense of all this." Which was not what the judge was asking at all (Yes, I did listen, like at least 12K other people).
thanks for the update Gramps. If anyone doesn't know about her, I highly recommend following Heather Cox Richardson on facebook. She is a Professor of History and writes a roughly daily post on national US politics, often setting the events in historical context.
ISIS didn't "hack" GETTR, they took advantage of a social media platform that made a big deal about how they don't censor anyone or bow to political correctnesscancel culture wokeness. Honestly, if that's the stand GETTR decided to take then some group like ISIS putting them to the test was inevitable.

Who would have guessed that a Trump-branded construction project would use a crappy design and fall apart almost immediately? I mean, besides anyone who knew anything about Donald Trump.
We should not forget seven capitol police officers have now filed against Trump, Roger Stone, the Proud Boys, and other conservative groups behind the Stop the Steal campaign leading up to the 6 January insurrection. CNBC story here
This may be a way of destroying some of the extremist groups behind Trump. A number of years ago, there was a group called the Aryan Nations in Northern Idaho. They were bullies. They intimidated many non-whites in the area. Law Enforcement could not move in on them because of their Freedom of Assembly and Freedom of Speech claims. But what did them in was when they forced a black woman and her son into a ditch outside their compound and assaulted them. The Southern Poverty Law Center sued and won a judgment that effectively killed the movement. That story here: https://www.splcenter.org/fighting-hate/extremist-files/group/aryan-nations

There has been some fact checking activity around a claim that the damage was caused by Hurricane Hana. It was caused by high winds in June, according to this article, but high winds and hurricanes sound similar to me. The core claims made in that twitter post strike me as true though. Rain comes with hurricanes AIUI. Reuters fact check.
I'm not seeking to attack @Crœsos for posting this. I've just learned to fact check stuff that tends to support my biases, especially when the post doesn't include supporting links like that tweet.

This sounds like an I swim/Fish swim/Therefore I'm a fish argument. The wall was wrecked by high winds. Hurricanes have high winds. Therefore the wall was wrecked by a hurricane.
I did a bit of reading on the construction of the wall (various segments) quite some time ago, and they all said that this was bound to happen, because a) too close to the water, therefore b) flood zone c) carrying debris that can't pass through and therefore exerts force, trashing the fence, and probably also d) crappy foundations, because building right next to a river, durrrrrrrrrrrrr. Which is difficult in any case, and there's no freaking way they did the over-the-top work necessary to keep it upright. Because $$$$$$$ and time (lots and lots of time).
So no, I'm not at all surprised it's collapsing. I believe there were enterprising folks with power tools making off with bits of it to recycle, long before the Rio Grande took a hand.

There's skepticism and then there's compulsive contrarianism. I notice you "fact checked" a bunch of claims that weren't in the tweet I posted. I'm sure those claims were made elsewhere (and probably over a year ago when Hurricane Hanna happened), but the tweet itself doesn't mention "Hurricane Hanna" (or "Hana"), does not contain a video (only one still photo), goes to the trouble of specifying where the photo was taken (near the San Bernardino Wildlife Refuge, which is in Arizona along the Mexican border, not far from the Arizona-New Mexico border), and even provides a link to the original photographer's Twitter feed from which one could find the original photo, if one were inclined to check facts. The original photo also doesn't claim to be in Texas, or anywhere near where Hurricane Hanna hit (a year prior to when that photo was most likely taken).
I don't know who it was here on the ship who, a year or more ago, recommended Trollope's 1873 'The way we live now'. Melmotte as Trump is kind of unavoidable, I think, if the book is approached today. I'm really enjoying it. Plus ca change.

It's fab, isn't it. I know Trollope has his many faults as an author, but he really could hit that human nail on the head when he analysed his characters.
Thanks, @Crœsos . @Anselmina , on the strength of this book I wouldn't dare list any faults - thanks so much for the recommendation. Even in his characterisation of Breghert as a 'greasy butcher' he seems to be daring the reader to acquiesce in-line with their own anti-Semitic prejudice, before revealing him (in his correspondence with the odious Georgiana) as being a man approaching even Roger Carbury's heights of probity.
It's great, reading a long, old book. Even someone with as shaky a vocabulary (and memory) as me, ends up thinking in words such as 'odious' and 'probity'
I know Trollope has his many faults as an author, but he really could hit that human nail on the head when he analysed his characters.
It's true that many of his books could do with a good editor (or Trollope not getting paid to stretch his story into three volumes to suit the publishers). Apart from that I think he mostly suffers by comparison with the other nineteenth century novelists we still read.
There are some areas where I think he's very good. He is able to pass moral judgements on his characters' actions without condemning his characters - something even George Eliot doesn't quite always manage. (Sadly I think he is casually anti-semitic, offset by the fact that he characters' humanity almost always break through. The only unmixed wrong'un I can think of is Slope.)
If anyone has been keeping count, up to 600 insurrectionists have now been arrested. 50 of them have pleaded guilty, with another 11 pending. The latest to plead guilty is Jacob Chansley, the QShaman. He has agreed to serve 41 months minimum for his actions. I find it very interesting how many have "seen the light" as a result of their arrests. Mother Jones Story Here.
Well, the Justice for J6 was a flop. There were only 450 protesters. There were more news reporters. Also, the pictures showed the crowd was mostly senior citizens (read: Baby Boomers).
In other news, the federal judge overseeing the prosecution of the Trump Organization for tax fraud has announced it is scheduled to go on trial on August 2022, just before the mid-term elections which will likely put a crimp on the impact of the Donald endorsing his people as candidates.
Yesterday morning, the wife and I watched CBS Sunday Morning. Ted Koppel had a report on how people still flock to "Mayberry." Watch the video at 10:13ff. Ted asked a busload of people if they thought the election was fair. Only two said yes. When he asked about January 6th, the majority of the people thought it was staged by BLM. And when he asked about how they viewed the media, well...

Wonder if those people know that Andy Griffith and Ron Howard endorsed Obama in 2008.
Andy Griffith was a staunch Democrat. He regularly endorsed Democratic candidates in North Carolina, and in the late 80s the state party tried to get him to run against Jesse Helms.

This illustrates Trump's culpability for the January 6th insurrection. No one showed up last Saturday because Trump didn't tell them to .
The strategy is the kind of cheapjack, legally tendentious bullshit we've* come to expect from Eastman, but the point of the strategy is to make some kind of semi-plausible legal claim that will simultaneously stir up the Republican base and force the American media into their reflexive "both sides do it" stance. Would it work with an angry mob storming the Capitol? Possibly. The one thing that seems certain is that the failure of this plan comes down to Mike Pence doing his job and that seems like the kind of "mistake" Republicans will seek to prevent in any of their future vice presidents.
