Perspective Styling

Where/how can I change the value & tick-mark text color on a gauge in a perspective view?

I’ve tried a local style as well as a class for white text on a black background; also tried different browsers and light/dark themes.
FWIW ~ in chrome inspector it shows the color being inherited from the containing div but the text is still black…

This is behavior is the same on various widgets. What am I missing?

i also have this issue, who can give some solutions
