Hi Annimaria,
1) best development tools has Chrome. Much easier to work with.
2)put this code to your Child Theme style.css file
OR
Install Simple Custom CSS plugin and put the code there.
.site-branding a {
color: red;
}
or
.site-branding a {
color: red!important;
}
OR
.site-title a {
color: red;
}
or
.site-title a {
color: red!important;
}
Change
red
color to any color you wish
Let me know if this is what you need.
Fell free to ask
Cheers

Follow UP!!!!
I just scrolled your site to the bottom and find out that your site is created on wordpress.com.
That will be problem.
When You have hosted free site there, there is not much to do with it.
Just basic settings.
I installed your Theme on my Hosting and there is no option to keep CSS in.
for that option to have CSS tweaking capabilities you need to install plugin like:
Simple Custom CSS as I mentioned above or to have Child Theme
So What I written above, will be out off topic.
You have wonderful business site so I assume you make money from that.
The best practice is to have hosted website, where you and your admin has access to more tweaking.
WordPress.com offers paid version, but I cannot say what you will get.
You are posting on WordPress.org and this is the place where mostly people have hosted sites with full control and it is choice No. 1 for the future.
I hope I cleared out this for you.
Let me know if you need any help with this.
I will be happy to help you succeed.
Cheers
