I know 16 colours is limiting, but one of my biggest pet peeves is CLI / TUI developers creating their own custom themes using colours outside of that because odds are, they’re going to generate a colour scheme that is harder to read for a lot of people with visual impairments, people who prefer a white or coloured background for eye comfort, people are dyslexic and find non-black backgrounds easier to read, and others with visual difficulties, reading difficulties, or those who just like a different colour scheme per project or environment they’re working in so they can multitask more easily.

And the developers answer to this loss of control is to create multiple colour schemes and allow the user to configure the app. Which then means their users have to set up their terminal defaults and then configure every fscking app that ignores those terminal defaults(!!!) instead of defining their required colour schemes once in the terminal.

People use the terminal not because it’s pretty but because they find a text interface more efficient. If you want to make pretty things then build a web frontend. But please do not break my terminal because you feel the need to impose on me your own favourite colours of the hour.

There are escape codes that can re-define palette entries. Usually including the 16-255 range.

Terminals like iTerm2 have had a Minimum Contrast for a while that messes with (foreground) colours, sometimes very badly.

This will be fascinating to see in practice, with ghostty for example shipping these changes! I expect that the concern you have here will largely be for naught, with some exception. What are some terminal apps you think might be affected, what are test cases?

I didn't read in fully, but what I was thinking in my head is not that we would just totally replace the rest of the colors with arbitrary palette. But that we would sub in better versions of the palette that also used user colors as the base. What was magenta is derived from what the user picked from blue and red.

There's always been such tension between design/creative and users. Apps & designers want their own brand identity, want creative control to make things just so. And are willing to throw user preference & desire on the pyre to get that exacting control. Personally that was always rubbed me extremely the wrong way; I would way rather allow some weirdness & funkiness in, if it leaves the user in control. But I understand the risk aversion, understand the Murphy's law corporatism that makes people and companies want to build strong laws that forbid anything but strictly approved systems, for fear that things go wrong. I understand. But I also things that's a dogshit world to live in.

Interesting. You could build a LUT from the 16 color palette to map the 24 bit color space to something 24 bits or less. A bit like mapping 10 bit HDR to 24 bit sRGB.

Perhaps instead of the application overriding the setting, it could be done with an environment var, so the user can easily override it if the mapping messes with the look/usability of the program.

I feel like you're saying one operating system does it better, but I fail to think of one.

Terminals are text. Text adds features missing from gui namely:

* Ad Hoc

requirements change and terminal gives ultimate empty workbench flexibility. awesome for tasks you never new you had until that moment.

* Precision

run precisely what you want, when you want it. you are not constrained by gui UX limits.

* Pipeline

cat file.txt | perl/awk/sed/jq | tee output.result

* Equal Status

everything is text so you can combine clipboard, files, netcat output, curl output and then you can transform (above) and save. whatever you like in whatever form you like, named whatever you like.

GUI apps are good for discoverability. They generally are not optimized for rapid use by power users though. That's of course not an inherent limitation of GUI apps, it's just that dominant paradigms hardly seem to consider power users.

I'm still annoyed and baffled by the fact that Ubuntu had searchable application menus 10 years ago, which were awesome and worked for just about any program, and then dropped them when they abandoned Unity. And neither KDE not Gnome thought to bring them back. In stead, many apps have since dropped application menus entirely, in favour of... some mishmash of icons and ad hoc menu buttons?

Also, even in the post-LLM era, building a decent GUI app is a lot more work than building a decent terminal app.

Graphical applications are great if your workflow mirrors the workflow that the GUI was designed for. However if your workflow differs then you’ll often be fighting the GUI.

Think of it like different types of programming languages. Some are more suited on different types of problems than others.

For me, my workflow is about composing and gluing different processes together rather than using a standard defined tool repeatedly in the same way as that tools UI was originally designed. So the CLI is ideally suited for me in all the areas where a GUI would be high friction.

Why? There is huge compatibility layer build on top of this and changing even these minor things will break stuff in places you do not expect. Want a fancy terminal? Install another one. By default most allow changing to many terminal formats. Break things to move forward is fun when it's not your problem to solve down the line.
