Request

Currently, the icon is the undermentioned:

As ProtonMail/proton-bridge#475 (comment) explains, it would function a lot better in custom colour schemes. That's why AOSP mandates monochromatic icons for its status bar and new Material You application icons.

https://github.com/blueman-project/blueman/issues?q=sort%3Aupdated-desc+is%3Aissue+is%3Aopen+monochrom returned 0 results, so I doubt that this is a duplicate.

You might be looking for gsettings set org.blueman.general symbolic-status-icons true to enable a symbolic status icon.

Indeed, I was, @cschramm. Thanks. I don't see that preference exposed via the GUI, so I've made #2480 (comment) to make it more easily locatable. However, I think it'd be worth setting as the default upon installation too.

[cschramm]

The primary purpose is distribution configuration, but user exposure would make sense, yes. I don't see why it should be enabled by default. Distributions that use symbolic icons can set the default themselves and otherwise fullcolor seems like a reasonable default. Monochromatic icon themes typically override the fullcolor icon accordingly.

@cschramm, I've not used a distribution that included blueman thus far, and on some OSes - like openSUSE Tumbleweed - the OS doesn't set these preferences, because it doesn't come bundled with a specific DE (it's chosen at installation time by the user).

Monochromatic icon themes typically override the fullcolor icon accordingly.

Can you elaborate on what you mean by this?

Yes, if the user chooses the DE or icon theme, he's typically left with setting the option himself. That's where it makes sense to provide it in the UI.

Papirus, for example, ships its own blueman icons; links to their monochrome bluetooth icons.
