Simple CSS setting (newbie) – font colour

Hi there,

Trying to change the body text in posts to a lighter colour as very difficult to read on black background. Thought this would be simple with CSS but can’t seem to make the font colour in the body of each post lighter.

My additional CSS looks like this:

@media only screen and (min-width: 768px){
.entry-content > .aligncenter, .entry-summary > .aligncenter {
margin-left: auto;
margin-right: auto;
color: grey;
}
}
p {
color: grey;
}

As you can see I’ve tried a couple of options!

All help greatly appreciated!
