Change color - all Social icons

Hello,
Im working on a Sydney-PRO child theme.
I created the social bar using the widget but the color of the social icons is red.
I need to change the color of all of them to white,

can you provide me the CSS to change social icons color?

I have to put it on “Additional CSS” tool?

Well, I figured it out myself.
I find that if you go to:

Page > builder > edit social widget > design > “Links color”

you can change the social icons color.
