December Theme – header colours will not change

Hi
PP Experts out there. I am trying to change the Header Text Colour to #fff in the Pagebuilder. Coding shows correctly however the end result is showing #454545. Cannot find anywhere to edit in CSS, and don’t know how.

Any ideas please

here’s a snippet from the page itself.

[pt_heading element_name=”Spotlight” heading=”h2″ text=”In the Spotlight” color=”#ffffff” align=”center” bgcolor=”#a5ad9c” padding=”10px,10px,10px,10px” margin=”10px,0px,10px,0px”
