Hey there @voboghure!
As Tapan mentioned that colors are coming from your theme.
But you can change them with some CSS.
I wrote bellow to rules that you can use directly into your WordPress Customizer. To try it go to “Appearance > Customizer > Custom CSS.
Feel free to change #000 to any other hex code that you want.
