How to change color of social profiles in top bar

There are green-colored social icons in the menu bar of my website, westchesternews.info

I would like for them to be blue, not green.

What element do i customize to make it so?

Thank you–

Elliot

p.s. I am still waiting on response as to why every time i edit any element on the page titled “news”,
most of the page gets deleted.

If i click on any block, the next preview shows everything deleted, except 2 boxes at the box i made.
If i click update the preview turns to reality.
There are no tags that are not closed, which could have caused error.
