How do I make a header a different color?

I have done some research and looked at other answers pertaining to this question but I still can't get it to work on my website, Roxsteady Music. I am trying to change the header of A Christmas Journey to red without the rest of the website going to red. Here is the CSS I used and it's still not working. Thoughts?

.collection-43c59d3dd6978b3a3 h1 { color: f0000c !important; }

I have also done this code with no luck either

 #collection-43c59d3dd6978b3a3 h1 { color: f0000c !important; }
