Icon color inverted in notification center

[ssrmm]

Hi,

I'm using the Microsoft.Toolkit.Uwp.Notifications NuGet package to show notifications in the notification center from a classic non-uwp application. Doing so I've run into an interesting problem. The application in question uses an icon that basically contains only a single hue. When displaying a notification the color of the icon is now automatically inverted/changed/adjusted in the dark theme (see below screenshots). By tweaking the color/brightness I can also achieve cases where the icon inverted in the light theme or even both themes. Places other than the notification center (task bar, tray icon) do not show this behavior. There is also no inversion happening as soon as the icon contains multiple hues.

Now I guess this behavior is there to improve contrast for purely black/white icons like the builtin Windows ones. In my case however the color inversion does not make a lot of sense because the icon needs to conform to company branding and inverting colors only really seems sensible for grayscale or maybe even monochrome icons anyway.

Searching for this issue does not yield any results really. I found that you can provide theme specific resources in packaged/UWP apps, but I couldn't find anything for classic desktop applications.

Is there any possibility to influence the icon choice in the notification center? Particularly, can I...

• turn this color inversion off somehow?
• specify theme specific icons for the notification center despite not being in a packaged/UWP application?
• specify an icon other than the EXEs application icon to be used in the notification center? In that case I could make the icon in the notification center white/black, but keep the colored version of the icon for different places.

@ssrmm Thank you for sharing this issue! Before the team can help with your questions, can you please tell us what Windows Builder Number you are seeing this (ex Windows 11 21H2 (Build 22000))?

I have seen this issue on the following builds:

• Windows 10 21H1 19043.1288
• Windows 10 21H2 19044.1826
• Windows 10 21H2 19044.1889
• Windows 11 21H2 22000.856

I've also pushed a reproduction case to GitHub: https://github.com/ssrmm/mwe-icon-color-inversion

With the specific icon in the example, the color gets inverted both with dark and light Widows theme.
