Header color and social media icons need changing

I’d like to change my header color, which I thought I had accomplished, but on the blog page and posts the header still shows up blue, along with the whole site in mobile view. I’m not really experienced with website building/coding, so apologies if I’m just being dumb here. Additionally, the theme has Google + and Linkedin icons in the header, and I’d like to change them to Instagram and YouTube, is this possible?

Thanks in advance.

Hello there,

You can manage the header background color in Dashboard > Appearance > Customize > Colors > Header > Background color.

To change Google+ to Instargam and LinkedIn to YouTube, add this simple CSS code to Appearance > Customize > Additional CSS from dashboard.

    .site-header .socials .fa-google-plus:before {
      content: "\f16d";

    .site-header .socials .fa-linkedin:before {
      content: "\f167";
