JPEG transforms the color into YUV channels. Y is the luminance, equal to R+G+B or something like that. The U&V channels (color) are often downsampled.
Y is basically "mostly green, a bit of red and hardly any blue" rather than a flat R+G+B. So blurring the green channel (as TFA does) is nearly equivalent to blurring the Y channel.
One of my favourite series in art is Yves Klein's blue work. For anyone unfamiliar, he found a blue that he considered the bluest possible blue [1], and went on a journey painting everything in that blue. I loved that he did this, and then eventually managed to get to an exhibition of his work at the Tate Modern and was absolutely blown away by it - it really needs to be seen in the flesh to appreciate it. There's so…
As someone who hasn't seen it in the flesh yet, and doesn't "get" modern art unless someone explicitly spells it out for me, could you elaborate more on why it's so spectacular? For example, Blue Monochrome [1] seems to my uneducated eye to be just a layer of pure blue that every wall painter recreates every time they paint a wall blue. Why is the Blue Monochrome piece more than just a wall painted blue? [1] https://…
Chemistry has DRASTICALLY altered painting from the Renaissance to the World War era. New pigments have been constantly highlighted and displayed in artwork. Finally, an insanely blue blue has been invented, bluer than any other blue paint in the past.
The artist highlighted above attempts to showcase the new technology in its purest form. Though, despite this strive for purity of blue, the application is inherently uneven. If you look into the painted canvas up close, you will see imperfections and patterns in "just a wall". It's also a statement, it may cause reactions and cause viewers to question the boundary between art and not-art.
It's not my cup of tea compared to masterworks of Van Gogh or Homer or any of the legendary painters, but art goes through many phases and is used to express many different ideas. What I do think is bonkers is that modern artists (who are well-connected) may be paid millions of dollars for these works, which to me don't showcase skill and talent, but which reward creative ideation and concepts.

You have astigmatism. I have a similar issue with blue when not wearing my glasses. I have 20/20 vision, but my astigmatism makes it difficult to focus on certain things. A computer being a big one. Blue light blockers help, but with proper astigmatism correction I don’t need them.
20/10 vision in one eye, 20/13 in another, no astigmatism. Blue LEDs in clocks when viewed at night look completely fucked up.

"Why these all-white paintings are in museums and mine aren't" [1]
There's an optometry place in my neighborhood with a back-lit sign with big, blue block letters. And every time I walk by at night I note how fuzzy it looks. I'm convinced this is an intentional troll. This optometrist knowingly picked a sign to make people momentarily question their vision.
This happens every wintertime for me as blue string lights are put up, and they always appear “fuzzy” compared to other colors.
Now I understand why blue in particular. Damage is done, I wish I could take it back.

I’ve never met anyone without some astigmatism; especially, people with other vision impairment. Astigmatism is the number one cause of night blindness which is what you described.
I don't believe the blurred images at the end have anything to do with eye focus, as the author suggests. After all, chromatic aberration is blurring of only a very, very small amount. The demonstrated seemingly negligible perceptual effect of blurring blue to a huge degree in a multicolor image doesn't seem to have anything to do with that, but rather the fact that we perceive primary blue as a much darker color tha…
I think that the title is a massive oversimplification because chromatic aberration by itself is not enough for us to be blind to the color blue. We do have cones that can detect blue for one. We are however, less sensitive to it so maybe the eye doesn't focus based on that channel(?).
I suspect that a plausible cause could be that there just aren't a lot of blue receptors in the retina, as the eye is pretty insensitive to blue overall.

Consider the time period and the historical context. It's modern times, Cold War is occurring, and WW1 and WW2 left scars across Western Europe and caused major changes in the art world, including being a boon to abstraction and fragmenting styles into many eclectic directions. Chemistry has DRASTICALLY altered painting from the Renaissance to the World War era. New pigments have been constantly highlighted and displ…
I was thinking something along these lines. Based on the first Wiki article, Klein was involved in developing this pigment. If so, the work stands on the merits of that achievement alone. He was, for that moment, literally the only person in the world that could have created that painting.
