Dashboard icons altered strangely after Core update. Is this a bug

Configuration Frontend
1

A Core update two updates ago, randomly altered some icons on my default dashboard to the Yellow/Gold color and shape shown in the snapshot. I have never seen this kind of weird change before. I have not changed anything for weeks. Is this a bug? How do I fix it?
I tried to find the backup that was taken as part of the update that caused this oddity, but could not see a backup that was labeled with Core Update backup anywhere! What happened to that backup? By the way, does Core and Front End mean the same thing?

As you can see, at least 2 issues here. I would like to file tickets but I find the HA ticket filing scheme rather intimidating, not at all straightforward, and I’m an ancient computer user familiar and reasonably comfortable with other systems. I’d appreciate any assistance you might have. Thanks.

I believe there was a breaking change to entities card use of state-color, it may be enabled by default now.

I don’t know what ‘shape’ you are referring to.

It’s pretty common feature of the HA UI now that icons are colored when their entity is on or in an active state.

Thanks karwosts. Never knew the entity icon was also intended to reflect its state - I always looked to the right of the icon to see the entity state.

Hello. I am not understanding how to remove those orange colors from the url above. Where exactly do I add the state_color: true too? Thank you.
