Is this normal with the countdown widget different colors?

I've never noticed a black color before just white. I wonder if this could be a bug on One UI 8. Phone S24 Ultra. You may have to click on photo for the whole image to show on here.

@catloverplayer I would suspect that the color chosen depends on the color of the image behind it. In the examples your provided, switching black for white (and vice versa) would make the overlay text blend into the background and be difficult to read.

The widget automatically adjusts the text color to be more visible against the photo background. Darker colors get white text, lighter colors get black.
