Titles/links of related posts are not in the color I want

Hello how are you?!

I'm trying to change the color of the titles/links of related posts on the articles page, however it doesn't change to the blue I want.

The titles/links only turn blue or when I place the mouse on top (hover) or when I access the page through the customize menu, as shown in the images.

How I want it to look (and how it looks in Customize): https://leonardomarioto.com/wp-content/uploads/2022/05/personalizar.png

How to access the article page: https://leonardomarioto.com/wp-content/uploads/2022/05/tela.png

Obs.: Obs.: the funny thing is that I have the same block of related posts at the end of the home page and there they are in the blue color that I want lol
