Re: "The aesthetic choices behind Lagrange?"
Hi there @skyjake! Thank you for your answer... I agree that typography and the layout make for a well "aerated" reading experience.
But to me, it's really the colors that do the trick!
Thanks for your explanations about how these themes are constructed, but I have a few more questions if you don't mind...
Like, is the color for the text just a lighter version of the background color, or is there some hue shifting as well? And is the color scheme choice based on the string for the url? Seems to be the case, since it's consistant across various devices...

The regular body text and the background use the same hue, yes. Note that there are light and dark variants of each color theme. In the dark variant, the body text color is indeed a lighter version of the background. Or more accurately the text color is a lighter version of the base color while the background is a darker version of it.
The "theme seed" that determines the random choices is a 32-bit hash value computed from the page URL or from a given user-defined site-specific string. The hashed part of the URL includes the hostname and a possible ~username.
(The hashing function was intended to be CRC-32, but I botched the algorithm a little so it's not exactly equivalent to it.)

@skyjake: Bravo! 👍

@skyjake: One more question, and then I'll leave you alone, promise!
So it seems that the background color is not the base color, rather a darker version of it...
On this very page for example, where is the actual base color represented?
I know I could go to the preferences and make experiments to get the answer, but I don't want to run the risk of messing things up!

Well, depending on how you define the term, the "base color" could be considered to be the background color of the page.
In the 'gmdocument.c' source code for the Colorful Dark theme, for example, the background color is used as the basis for many of the color calculations, however the background itself is based on the "primary hue" that is the true base color of the theme. The primary hue is a fully saturated color so it can't be used as-is since that would be too overwhelming.

@skyjake: Thanks man!

Thanks for the reference @clseibold. The max page width in Lagrange does make the text less intimidating!
The aesthetic choices behind Lagrange? — Hi! I'm really fascinated with Lagrange, and how it made me fall in love with reading pure text again... A big part of the merit goes to the Gemini protocol itself of course, but in my case I attribute it mainly to the way Lagrange deals with colors. So I tried looking for info on how it's done, but I only found a technical publication about ANSI escapes and such. Do you guys have links to a more color-theory / aesthetics oriented article about this...
