Change article Title color on hover

Is there a code I can put into custom CSS to change the article titles color on hover for all of my pages? I used to use a code that worked for the home page but I had to change my homepage do to issues with updates so now I need a code to change the article titles color on hover. My site is www.technowolf.com

Here is the old code I used which no longer works and only worked for my home page previously. I want the article titles to change color on hover on ALL of the pages. Thank You.

article.page .entry-header h1.entry-title a:hover {
color: #a50010;
font-weight: normal;
}
