Can't seem to change fonts color

Hello all,

I have been working on this problem for months and now I am just gonna ask myself.

How can I make sure that if I change a color of any font on a page with the wordpress menu it also shows? Now it just keeps being this boring grey type.

I know I have to change something in my stylesheet CSS or something? But what, I tried a lot already.

Below is my code, PLEASE HELP ME.
