Hi James, is it possible to provide the page URL so we can have a look?

James,

plz try this in customizer -> additional CSS

.light-content p, .dark-section p {
    color: #ffffff;
}

to change the color of all paragraphs against dark backgrounds

p {
    font-size: 18px;
    line-height: 36px;
   }

to change the font size and the line height

Plz let us know if this works for you

Hi James, you are not being dense, we specifically set the color of the paragraph for design reasons.

That is, for example, the paragraph text on dark backgrounds

the theme paradigm (if you like) is black vs white contrasts

that's overwriting the settings you have using Elementor

Hope if makes sense, we can delete these css codes that purposely set the paragraph colors in the theme's .css files using Appearance -> theme file editor

Now, the css code I've sent in my prev comment are setting new colors for all paragraphs if you modify the hex codes and add to customizer -> additional CSS

Sounds good James
