I'm just reporting this problem. I don't want to fix it.
This is your friendly Microsoft Issue Bot. I've seen this issue come in and have gone to tell a human about it.
Thanks for the feedback! In this case, we are aligning to the pattern other Windows applications that are receiving new Fluent icons are following, so closing this as by design.
@grochocki Is not using the accent colour part of the Fluent Design System? I'm confused. XAML Controls Gallery uses the accent colour. Should that be updated? And on Windows 10 v2004, the Office tiles have dark grey tile backplates instead of blue, white/black, coloured or accent coloured backplates.
I understand that Microsoft will be ditching tiles (I've expressed my thoughts on this on a doc issue) but Windows 10 still uses tiles right now and my start menu looks very messy. Anyway, even once tiles are gone, what'll happen with splash screens? Will they be white/light grey or black/dark grey? And what about the app itself? Will accent colours be removed entirely?
@grochocki Even Windows Terminal uses the accent colour for its tile.
We really appreciate the feedback, @Poopooracoocoo, and I have shared this feedback with some folks internally -- if you’re interested, the design team posted a concept here with a vision of how we are considering improving the Start design.
@grochocki so Windows will be using grey/light grey acrylic tiles. Hmm. Doesn't seem right. I thought Windows would go all in on ditching tiles. Anyway, that's way into the future. We still have actual tiles right now and apps that haven't customised their tiles still use my accent colour. Will calculator and the other apps use my accent colour?
and wow the padding is just so extra. reminds me of the ol' project neon concepts. the whole gif is a little weird. windows will be removing app names from tiles too? idk whats goin on
@grochocki funny how jen's response is the same:

changing the default is one thing, changing the custom colour is another. If it's by design, this change should be implemented by the shell, not by the apps. and even then, why isn't calculator going with the dark grey that the Office apps went with? Why hardcode blue???
erm. @grochocki idk if you saw my message. im pretty confused
@Poopooracoocoo This doesn't make much sense anymore, as with the Windows 10 20H2 update, the app tile background will follow the system theme colour instead of the accent colour.
And this will apply to all apps, so there is no question of inconsistency.
@Rahul-Dixit Yeah I know. The splash screen still doesn't use the accent colour. Hence why I made that other issue that's linked above your comment And they _ONLY_ made that change to the Start menu.
