Active message highlight colour in Thunderbird is bright blue

Hi there,

At some point during the day, the highlight colours in Thunderbird 78.6.0 started displaying as bright blue. I was not changing any settings at the time and cannot find a setting to change it back. At first I thought it was a system setting, but this appears to be isolated to Thunderbird only.

As you can see in the screenshots, this is happening in both the calendar and my mailboxes. I am using the stock dark theme and have never had issues until today, and I have tried starting in safe mode already.

Any advice on what may be turned on/off?

Thanks

I guess windows 10 did one of it's wallpaper/theme changes then.
