ar33bshola yes, add the following CSS to Admin > Appearance > Custom Styles > click on Edit Custom CSS:
.TagHero .Hero-title {
color: white;
}
You can replace “white” with any CSS-valid color (https://www.w3schools.com/cssref/css_colors.php) or color code (https://www.w3schools.com/colors/colors_picker.asp).
NB I don’t think there is a way in Flarum to change the tag text without CSS, might be a bug that the color is calculated incorrectly according to primary/secondary color, unsure
