How to customise font colour in Parallax

I’m using multiple Parallax sections for my site.

I would love to be able to have white text for one section (over dark image) and then black text for another section (over white background).

How can I do this for specific sections?

Hello there,

I hope you are doing well today.

Could you please provide a link to your website so that I can inspect it?

Best Regards,
