Can't change the paragraph color on blog body

Hi, I’m trying to change the color on the paragraph font on my blog, but when whenever I change the color on my “blog-post-body” element, it only changes the color of the headings. How do I change the color of the paragraph font?

Here’s a quick video of the issue: Loom | Free Screen & Video Recording Software

Thank you!

Hi @Ron_Harnik you need to make changes in RTE it self (for anything).
