Changing Text color on Pages

So, I have seen a lot of post on changing text color, and I used the css recommended in those post to change the post on my website to black. Unfortunately, the css I used does not appear to affect the text on pages. At the moment, the first paragraph on all of my pages is black, and after that it turns into a faded grey. Is there a way to change this? My site is Thanks.

Hi there

This happens because of your cutom css code:

/Paragraph appearance/ p {
font-size: 15px;
color: black;
font-weight: 400;
line-height: 25px;
margin-top: 10px;

.single-post .entry-content p:first-of-type, .page .entry-content p:first-of-type {
color: #001936;
border-bottom: none;
padding-bottom: 0px;

You need to remove it or change the rules
