change the yellow color

Are you using a plugin for that? Which one?

No, I added hand

I don’t know that you can change that color – may be AdSense controlled. A browser tool like Firebug should show you the CSS IF it’s possible to change. Are you using a child theme so that your changes to the theme are not lost when WP is updated.

I checked with firebug and adsense but .. I found nothing ..

For any additional CSS help, we need to see your site.

thank you https://blog.wrooom.net/
I also checked with another browser (Chrome) but it’s the same

Firebug shows it here:

ins {
    background: none repeat scroll 0 0 #FFF9C0;
    text-decoration: none;
}

Are you aware that all of your changes to theme files will be lost when WP is updated? It’s extremely inadvisable to modify theme files – you should be using a child theme –
