Changing the Default Text Color for Big Number Charts

[enes-ozturk]

Hi,
We are using Superset 4.1.2 in our project, and I have a question about the default color for the big number charts.

I have some big number charts, some of which have conditional formatting enabled. Superset seems to set the color of the values programmatically on the HTML element. For the ones without any conditional formatting, Superset sets the value's color to black. I would like to change this default color to something else by using CSS without affecting the other big number charts with conditional formatting in the same dashboard.

How can I achieve this in Superset?
