Changing Background-Color

is there something wrong with the "warning" variable in this code?

app.js 
var warning = document.getElementById("warning");
var button = document.getElementById('makeItRed');

button.addEventListener('click', ()=> {
  warning.style.background-color= 'red';
} );
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>Adding an Event Listener</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <div id="warning">
            Warning: My background should be red!
        </div>
        <button id="makeItRed">Make It Red!</button>
        <script src="app.js"></script>
    </body>
</html>

background-color works in CSS. In JavaScript it is backgroundColor
