+## “The most radical thing you can do is care”
+
+A lot of folks in my network are sharing Dan Sinker’s reaction to the news
+about the sloppy LLM-generated “summer reading supplement” that was published
+in a couple newspapers, and I’ll join them.
+
+For inscrutable and personal reasons, I think it makes a good companion to [28
+slightly rude notes on
+writing](https://www.experimental-history.com/p/28-slightly-rude-notes-on-writing)
+from Adam Mastroianni.

+## The OKLCH color space
+
+I love color, even though I don’t see it the right way: a not-uncommon color
+deficiency[^colorblind] means that I muddle certain combinations, e.g. browns
+and greens, or blues and purples. Nevertheless, I’ve long been obsessed with
+Joseph Albers’s _Interaction of Color_, and give more thought to the color
+schemes I use for my data visualizations and other digital artifacts than is
+sometimes appropriate. I was always frustrated that CIELAB didn’t see broader
+adoption by designers, even though the advantages of a (somewhat) “perceptually
+uniform” color space seemed self-evident to me.
+
+So I was stoked when I stumbled upon the OKLCH color space---which [Björn
+Ottosson developed to address some of CIELAB’s
+shortcomings](https://bottosson.github.io/posts/oklab/)---and learned that it
+has become widely adopted in web browsers and graphics programs in the past
+couple years[^old]. The color picker below is a great place to start exploring.
+My only concern is related to colorblindness: using this color space, it’s _too
+easy_ to make colors that differ only in hue, which is generally a bad idea for
+displays.

+
+[^colorblind]: I’ll casually describe myself as “colorblind” but I actually
+ have “deuteranomaly”; I have three different kinds of cones like folks with
+normal color vision, but my M-cone is a little _off_.
+
+[^old]: I missed this because Debian 12 is stuck on Inkscape 1.2.2, and this
+ feature was added when 1.3 was released nearly two years ago. This is why
+people make fun of Debian stable users.
