Tested on pantheon nixos-unstable, seems to work

The problem is probably that it's not in your environment.systemPackages. Unsure if this is a bug then 🤔

[doronbehar]

There's also the *icons packages such as breeze-icons which may help.

[doronbehar]

@davidak did you try to install breeze-icons?

[davidak]

Having breeze-icons don't help:

nix run -f channel:nixos-unstable pick-colour-picker breeze-icons -c pick-colour-picker

But installing it using environment.systemPackages does, even without breeze-icons, on stable.

I think it should also work with nix run.

[doronbehar]

I think it should also work with nix run.

I agree, sounds like it's wrapping related - on my system:

$ echo $XDG_DATA_DIRS | sed 's/:/\n/g'
/nix/store/hypvzdxqbdkc2bilp42ldbk1a9xk04h5-gtk+3-3.24.20/share/gsettings-schemas/gtk+3-3.24.20

/etc/profiles/per-user/doron/share
/nix/var/nix/profiles/default/share
/run/current-system/sw/share

And in /run/current-system/sw/share, I have:

$ ls -l /run/current-system/sw/share/icons
total 12
lrwxrwxrwx 1 root root  89 Jan  1  1970 Adwaita -> /nix/store/r0j7nv84y8dvnk52xxkv0iyrkrdn5wnh-adwaita-icon-theme-3.36.1/share/icons/Adwaita

So I suspect the icons are loaded from there. If we'd wrap pick-colour-picker properly we wouldn't encounter this, but that's impossible with our current wrapping methods, if you ask me. Anyway, I added this to my TODO for my declarative wrappers enhancement and I'll write an RFC someday for this, examplifying this issue.

No breeze-icons but it still works. And that should also be accessible in nix shell, but packages should also work in pure shell.

The issue is still reproducible.
