Faded colors with solarized light?

[djbpitt]

What version of fd are you using? fd 8.2.1

In iterm2 (Build 3.4.15) fd renders several colors in pale pastel hues that cannot easily be read against the background because of insufficient contrast. ls -G does not have this issue. My iterm2 settings are:

• General tab, Theme: Light (High Contrast). "Brighten bold text" is checked.
• Profiles tab, Default profile, Colors panel, Color presets drop-down: Solarized light

LS_COLORS is not set.

I'm not wedded to "Light (High Contrast)" or "Solarized light", but my vision is imperfect and I can't read the screen with dark themes, so I do need something light (but not a bright white background) with strong colors and strong color contrasts. I don't have this issue with any other application that produces colored text output in iterm2. Are there iterm2 settings or fd options that would enable me to render output from fd that is no less legible than the output of lg -G?

[tavianator]

Can you paste the output of

$ ls --color=always path/to/file | xxd
$ fd --color=always -p path/to/file | xxd

where path/to/file is a file with different colors for ls and fd?

Thank you for the quick response. Here is the output:

Ah I forgot fd has a default color scheme that's used when LS_COLORS isn't set. If you set LS_COLORS to anything (e.g. the empty string), it will match GNU ls.

[djbpitt]

@tavianator I set LS_COLORS to the empty string and I see just two shades of gray. Here's the output of both fd and ls:

[tavianator]

Do you mind trying it with both ls and fd command lines that match only a single file? It would be easier to compare that way.

Also, can you paste the value of the TERM environment variable? Thanks

@tavianator

In the first tests below, I'm in a test directory that contains a single regular file called stuff.

djb@koala-4 test % set | grep -w LS_COLORS
LS_COLORS=''
djb@koala-4 test % set | grep -w TERM
TERM=xterm-256color
djb@koala-4 test % ls --color=always | xxd
00000000: 7374 7566 660a                           stuff.
djb@koala-4 test % fd --color=always | xxd
00000000: 1b5b 313b 3334 6d2e 2f1b 5b30 6d73 7475  .[1;34m./.[0mstu
00000010: 6666 0a                                  ff.

Apparently regular files are not colored by ls with my settings, but when I change stuff from a regular file to a directory I see:

djb@koala-4 test % ls --color=always | xxd
00000000: 1b5b 3334 6d73 7475 6666 1b5b 3339 3b34  .[34mstuff.[39;4

Ah okay, I see. ls is not bolding things by default, while fd is. I'm guessing you're not using GNU ls, since its defaults should match fd. I can reproduce by switching to Solarized Light and running

What's happening is that most terminal emulators use the "intense" color palette when rendering bold text. But the Solarized Light "intense" colors are pretty monochrome (except for red, for some reason). You can use the 256-color escape sequence instead to force it to use the regular palette:

Here's a Konsole bug about this, btw: https://bugs.kde.org/show_bug.cgi?id=405345. Looking back at your original post, what if you uncheck "Brighten bold text"?

[tavianator]

^ The above comment is relevant to the LS_COLORS='' behaviour, not so much the unset LS_COLORS behaviour, which just uses a theme that's hard to read on a light background. We might want to pick a more neutral default theme that works on both light and dark backgrounds.

In the meantime, you can use something like vivid to generate an LS_COLORS theme that will look better with your terminal theme. For example:

[djbpitt]

@tavianator I'm using the default (MacOS, that is, BSD, I guess) ls.

With LS_COLORS set to the empty string, unchecking "Brighten bold text" enables fd to render colors that are legible against the solarized light background, that is, it resolves the issue. It hadn't occurred to me that "Brighten bold text" would interfere with rendering color; what I thought (apparently incorrectly) was that brightening was independent of color.

There is still a difference in the way fd and ls render colors: the fd version is bolder:

djb@koala-4 test % fd -d 1 --color=always . | xxd
00000000: 1b5b 313b 3334 6d2e 2f1b 5b30 6d1b 5b31  .[1;34m./.[0m.[1
00000010: 3b33 346d 7374 7566 661b 5b30 6d1b 5b31  ;34mstuff.[0m.[1
00000020: 3b33 346d 2f1b 5b30 6d0a                 ;34m/.[0m.
djb@koala-4 test % ls --color=always . | xxd
00000000: 1b5b 3334 6d73 7475 6666 1b5b 3339 3b34  .[34mstuff.[39;4
00000010: 396d 1b5b 306d 0a                        9m.[0m.

This isn't a problem that necessarily requires a solution. Your description of the original issue as originating in a default behavior with unset LS_COLORS is consistent with the behavior I saw originally. Setting LS_COLORS to the empty string and unchecking "Brighten bold text" in the iTerm2 configuration is (now that you've explained it!) an easy fix. Thank you for your help!

Right, I should have guessed this from "iterm2" :)

There is still a difference in the way fd and ls render colors: the fd version is bolder:

Yeah, that's expected. fd follows GNU ls here, which bolds most things by default.

You're welcome! :)

I'm going to leave this open because I do think we should consider changing the default color scheme to work okay with light terminal themes. @sharkdp how about ayu? It looks good to me across a few different Konsole color schemes.

[sharkdp]

It looks good to me across a few different Konsole color schemes.

You mean.. for both dark and light background themes?

We have a similar problem in bat where we now decided to implement a way to detect dark/light backgrounds (at least on MacOS) because there was no color scheme that was working for light and dark themes. But fd is a bit different here, as we don't need that many colors probably.

[tmccombs]

at least on MacOS

Is there a way to do this that works on all (or most) platforms?

[tavianator]

Yeah.

Is there a way to do this that works on all (or most) platforms?

bat does it like this, which is macOS specific (and maybe only applies to the default terminal emulator?) https://github.com/sharkdp/bat/blob/3339eee2dc34d350f7c91b4c860084306196acf0/src/assets.rs#L402-L410

However, there are some other ways to get that information. Some terminals support a COLORFGBG environment variable; here's a neovim example.

But the best way is probably the OSC sequences, which are sparsely documented, but you can ask for the current background color with \033]11;?\033\, and xterm-compatible emulators will output something like 11;rgb:fdfd/f6f6/e3e3 (which is #FDF6E3) or 11;rgb:0000/0000/0000 (which is #000000 of course).

The syntax comes from X11's XParseColor. Apparently some terminals will output rgba:RRRR/GGGG/BBBB/AAAA instead. I kinda hope there's an existing crate for this...

[tavianator]

I found https://github.com/dalance/termbg

[sharkdp]

Hm. Are we sure there are no downsides to this? Like some runtime penalty. Or compatibility problems where some users would see seemingly random garbage on the screen?

[tavianator]

Well I read through the termbg implementation and it's not perfect, but conceptually it can be done without a delay and without the chance of users seeing garbage. I prototyped something but I'm not sure if I should publish it as it's own crate or contribute it to crossterm

[joelparkerhenderson]

Same kind of issue on macOS Ventura with default macOS Terminal.

Image:

The fd 8.5.3 command shows colors that are quite hard to read IMHO: directories appear light sky blue, and files appear light pale yellow.

Terminal app uses default white/light background. The ls output looks fine, and not at all like fd output. LS_COLORS is unset.

When I export LS_COLORS='' then fd changes: directories appear as dark bold blue-purple, and files appear as black.

Expected: fd to be easy to read on default current macOS default current Terminal app. Also that fd would treat unset LS_COLORS the same as empty string LS_COLORS.

Actual: fd output is too light/pale to be readable to me.

[jheidbrink]

Would it be an option to make fd behave per default as if it had been called with env LS_COLORS="" fd? In my understanding this would work out of the box with all terminal colorschemes , and wouldn't require extra logic to determine if the terminal colorscheme has a light or dark background.

[chrisgrieser]

I also want to emphasize that this should be fixed instead of leaving it up to the user to add export LS_COLORS=''.

It's also noteworthy that setting LS_COLORS to '' also makes exa loose all colors.

So to make fd and exa work at the same time, you have to add this to your rc file:

export EXA_COLORS="$LS_COLORS"
export LS_COLORS=''

[soloturn]

this is not only broken with solarized, but with gnome white background terminal as well. fd makes a difference if LS_COLORS is set to empty string, and not set.
