Windows application dock icon themed for Mojave dark mode

Hello,
in Parallels 14 Mojave's dark mode works great except for the windows applications folder icon (the one that is by default placed in the dock nearby the trash can), which remains lighter than the others when entering dark mode.

this is just a visual glitch that should be easy to fix, I suppose you just need to add a darker version of the windows application folder icon.

Sample is attached.

Thanks.

 

Yes! Makes my eye twitch

 

Anyone find a replacement icon? We can update it ourselves via Get Info on that folder. I just need an icon to copy/paste on it.
