Nah her point wasn't "Everyone should be making their clothes from scratch and you are a loving idiot if you don't!!" her point was more about hey maybe things should last longer than they do and learning to repair stuff yourself isn't a bad idea. Like it wasn't a particularly deep point, she just made it well :shrug:

It was well known in the 20th century that colors could be reproduced by mixing primaries, I think western civilization figured that out in the times of ancient greece but I don't know the exact history. And I think it was also known that although all hues can be made from three colors, all hues aren't made of three colors by the time of Newton.

By pure coincidence, two scientists in the 1920s, Wright and Guild, designed identical color matching experiments. You would look at a neutral grey ball that was lit on one side with a pure color, a single photon wavelength, and on the other side you had knobs that could control pure red, blue, and green lights, and the goal was to match the colors.

The scientists, independently and unaware of each other's experiment, tested on several people and found their subject's answers to be surprisingly consistent. But there was a problem with some colors, like cyan, where no combination of red, blue, and green could reproduce the vividness of the pure, reference cyan. So the scientists allowed the subject to get as close as possible, and then they added another set of red, blue, and green lights to the reference side. And then by adding some red to the reference, pure cyan, the subjects were able to match the color. So the scientists marked this down as 'negative red'. The left graph below is the 53 participants from both studies' results superimposed. At the time (1920s/1930s) this color mixing was computed using matrix math by hand, and negative numbers greatly complicated the math, so a stretching and rotation of the colors was done to make all colors have positive values, but the result was that the space, called XYZ, had a lot of empty areas where you had coordinates that don't respond to human color perception.

When the scientists learned of eachothers work and compared results they were astonished how well their data matched. In 1931 a commission was formed to standardize a model of human color vision. Here's the results, you can see the triangle of RGB with 1 in each dimension representing 100% on the dial, and then all the negative values needed to accurately represent colors. The 'x' axis here is red (not to be confused with the X coordinate in xyz. It's easy to do rotations and stretches of a space with matrices so they picked some points and rotated it.

Since there are many ways to rotate and stretch this thing, another decision was made to try to make the Y axis relate to perceived brightness as much as possible. A dozen 555nm green photons (where our eye is most sensitive in color vision) will look as bright as thousands of 650nm red photons. They basically nailed it, except that perceived brightness has some non linearities. As an aside, This is why it's hard to cover a lot of the XYZ horseshoe with a RGB display, you can pick a deep red primary for your red pixels but you will have to drive it with exponentially more power to make it as bright as the green primary, which means more energy and more heat.

The XYZ chart has a nice linearity in that if you pick any two points, then any points that lie on the line between the points you chose, are colors you can make using the points you chose as primaries. So if you pick to points, build lights that emit that color, and shine them on a white surface, as you dial the lights up and down in brightness you will see all the colors on that line. So any two points whose line goes through D65 can make white light.

Later, another test was done where subjects were shown a color, and allowed to turn the reference knobs until the two colors became distinguishable. The areas of indistinguishability were drawn as ellipses on the XYZ chart and you can see the distortion (the ellipses drawn are scaled up 10x in size so you can see them and their distortion easier). Area in the chart does not line up well with the amount of distinguishable colors found there, the ellipses below represent areas of color that 'look the same' as the point at their center.

So a different stretch and rotation was made in 1974, with coordinates called LUV instead of XYZ, that compensates for that, here they are also drawn 10x in size. This gives a better sense of the space of colors we experience. The 'plankian locus' is the color of a blackbody as it heats up to infinite temperature, from red hot to white hot, because these are a great reference for white and you can see the curve goes through D65 - 6500 kelvin. That's what color temperature means.

A guy named Pointer went out and measured every pigment he could find, because although we can see all these colors when we shine light through a prism or make a laser, that doesn't mean that we can paint them into a painting and see them just by shining white light onto the paint. So what you see below inside the squiggly line are all the colors that exist as colors of objects on earth, and you can see it's not even half the area of what we can see looking at emissive sources, like lasers, neon signs etc that can emit pure color (rather than reflect it like a pigment)

Finally, the white triangles below contain all the colors that can be reproduced in the different display standards that are used right now. HD TV standard 'Rec 709' which is the same color primaries as the computer monitor standard 'sRGB' were the standard from 1990 until about 2020 and they were followed pretty well. Apple makes its screens display a wider color gamut, the same as digital cinema projectors, which is called 'Digital Cinema Initiative - P3' or just P3. P3 covers reds much better and greens a little better than sRGB. TV's have moved over to a new standard called Rec2020, designed to try to cover all of pointer's colors (pointer's gamut) which is much larger than either of the other two, but as far as I know, so far no TV has exactly hit the standard and so it does some kind of interpolation.

sRGB/Rec709

DCI-P3

Rec2020

Now that HDR is possible and consumer products are trying their hand at it there will be more new standards and it's all very chaotic. HDR also just means brighter colors, not more colors like some advertising claims.

they have played us for absolute fools

yeah an important thing to recognize from a marxist or at least materialist perspective on history is that for a large chunk of human history the plurality of all economic activity was in textiles, often even more than farming

but the plurality of that work (at least, if you were using flax, hemp or wool) was spinning, which is largely invisible to most histories as women's work

RGBW lights can't do saturated yellows or cyans as well as a gel on a leko. it's okay for small adjustments but if you want lime-teal colored light they suck. Tho that's why the older color stage lights have like 7 or 8 colors in them.

no one gives a poo poo if the teal is not a 'nice' teal though I guess

edit: and god help you if you mix LED brands and do some strong teals or cyans. it can be a real mess

LED colors are based on material bandgap, dopants, structure, and other things

they can also have phosphors

here a blue emitter is pumping a phosphor to get a better white

as such there can be gaps in the emitted spectra and while your eye DOES do color mixing it doesn't mean you can make super precise or good colors from it

Another question - I was part of a trial to change vehicle and command post interior lights from red to blue. I know red preserves your night vision, but not why, and also that you can�t tell colours apart, like when you�re reading a map. With the blue light I suppose you could, but isn�t the blue light in screens what�s causing everyone problems? You�d think it would also ruin your night vision and maybe get seen from further away?

e: Is it true that Navy Blue and Rifle Green are so dark because they guaranteed uniformity by dumping lots of pigments in the dye to be sure?

echopraxia is� I don�t want to say bad per se but is not nearly as tight a story as blindsight and has a lot of �cool idea� followed by �here�s another cool idea. it has destroyed the previous cool idea�

I also agree that I feel like he blew up the ending of blindsight for no reason, but �but how do you know they�re still a real person� part is interesting and a valid read of blindsight at least.

I�m kind of reminded of Hitchcock describing suspense as a ticking bomb that doesn�t go off action being the bomb going off. except in this context it�s the suspense of an enemy nuke traveling towards you except surprise your nukes already went off so :shrug:

The bit in your eyes that controls how much your iris is dilated doesn't respond to red light as much, so your irises stay dilated to let in the most light and not leave you suddenly needing to adapt if the lights go out entirely.

Not sure why they would switch it to blue light. I do know that the "blue light is causing all of society's problems" thing is one of those pop science topics that's full of landmines and nowhere near as cut-and-dry as a lot of people would have you believe. Maybe if you used a lower intensity blue light you could still keep it low enough so your irises don't constrict, but be better able to read stuff? The eye is least sensitive to red light in general which makes it harder to see in red light than the same intensity of other colored light. Though I'm not sure if color perception would be any better - if it's solid blue light, everything's just going to look blue, grey or black.

I liked Echopraxia but I think a lot of people read it and found the side parts of the first book they tolerated were now the main course. There's no face to face battles with an alien intelligence like in the first one so if you just tolerated the big themes to enjoy that weirdness you're probably going to hate the 2nd book.

I certainly didn't like it MORE but it was a better followup than the Rifters series had imho, though I think the themes and settings Watts works in don't really have good ways to keep the train running beyond a book or two. Occupational hazard from starting one step from the big unavoidable total catastrophe I suppose.

Armadillo Tank posted:

The idea of pointer's gamut is to map all the natural things you could shine a pure white light on and observe with your eye. The reason that's useful is if you cover pointer's gamut with your display there's no real world imagery it cannot faithfully reproduce, even the deepest blues in the heart of a sapphire or the greenest tree frog. The exception being emissive sources like neon signs and laser light.

Due to the curved nature of the XYZ chart there are no 3 primaries (no triangle) within the chart that can reproduce all the emissive stuff at the edges. But real color displays must use colors from within the horse shoe (the area outside on the graph is unphysical) and also want to use 3 cause that's the least you can get away with. Some HDR screens are RGBW - they add white just to get the brightest brights brighter, and bright things usually look desaturated so you don't worry about losing color information.

I was talking about pigments in paint as an analogy to a screen but it's more about reproducing the totality of real world images. You can see Rec2020 doesn't cover a few points, but also you can see that if you move any point of the triangle you will cover even less. I think the best TVs now from Taiwan cover about 80% of Rec2020 which is pretty far off spec.

I'm a small-time musician, and over the last decade or so most local venues have converted to LED stage lighting. It's neat to have a wide variety of colors available and not get roasted under a heat lamp onstage, but a lot of the colors feel oddly cold, unnatural or one-dimensional; and also digital photos can turn out pretty bad.
