In the article widget, the font colour in the title options has no function.

Update:
Solution: in framework/elements/articles/articles.php after line 222
Style::renderTypography(‘#’.$element->id.‘ .astroid-article-heading’, $title_font_style);
insert the following line:
Style::renderTypography(‘#’.$element->id.‘ .astroid-article-heading *’, $title_font_style);
