Mailspring: Implement a dark tray icon for light themes

[nihil21]

What operating system are you using?

KDE Neon Developer Edition Unstable

What version of Mailspring are you using?

1.2.1-7e7447b6 snap

Feature Request?
Hi, as you can see in the screenshot below, currently mailspring displays a white tray icon even in light themes:

So I was wondering if it would be possible to make mailspring recognize the theme in use and display the correct tray icon (in this case, a dark one), though I think that snap confinement wouldn't allow that. Maybe implementing a switch from which you can manually set the correct tray icon is more feasible, what do you think?
Thanks in advance.

Hey! Ahh this would be super cool - do you know how KDE normally exposes the theme tint color / light vs dark setting? I know we get a few environment variables through the Snap daemon, so we might be able to do this if it's one of them.

Unfortunately I don't know how KDE does that

I second this request. Would be great to have dark icon for light themes.

Plasma doesn't distinguish between light and dark themes, there's just colour schemes.
You can read ~/.config/kdeglobals to get the colour palette of the active colourscheme.

And if your icon is an SVG, you can even embed a stylesheet into it that allows it to conform to the active color scheme: https://cgit.kde.org/breeze-icons.git/tree/icons/status/16/battery-050.svg

This still hasn't been fixed, I get a white icon on light background using KDE Plasma with Breeze theme. Perhaps a custom fix could be made when it detects "Breeze" (but not "Breeze Dark") as the theme, as many users will be using it as its the default in Manjaro etc.
