Bugzilla

Windows 10
In version 78.4.3
Using Dark Mode.
Testing in Safe Mode - I see same as you, but that is only on the Inbox.
Also it doesn't help if people happen to have set the colours of their folders in that same or similar blue colour.
And yes, my folders were given a blue colour because yellow no longer works very well on a dark background when the chnage of colour only chnages the outline and you need a solid fill.  In the end I had to completely remove all the new icons which turned out to be useful in the Support Forum due to several users needing a return of use to original folders.
People have the ability to set whatever colour they like. So changing colour on it's own is no longer a satisfactory solution. That went out the window when the new design for Folders came in.

Biggest issue:
I have message filters that send new emails to folders eg: Thunderbird, Bugzilla, Family, very few emails actually arrive and remain in the Inbox.
Those folders receiving new mail have no change in colour.  Not that a change in colour is satisfactory anymore due to new design.

Text of folder name does become bold, but the bold whitish colour is barely distinguishable from regular. It's not immediately obvious.

What is required is to Create a folder svg with a gold star and use the same old code as before to enact it.

But no blue text in anything other than Inbox.

 OR at the very least the folder name should change colour in the same way that the Inbox changes colour.

This is a bug.  There is no indication of new mail in general folders as was the case prior to changing all the icons in the Folder pane.
