Background Image for home page

Background Image for home page.

Can someone help me narrow down the css to have a different background image for the home page than the one I have set as the default.

I have the default background image set for this class
.page-template-default

but
.home .page-template-default
does not change it for the home page.
Is there a css that will work?

I would like the fix to show this image.

.home .page-template-default {
background-image: url(“https://frankfulton.ca/wp-content/uploads/2018/07/BackgroundColor5.png”);
background-position: left top;
background-size: auto;
background-repeat: repeat;
background-attachment: scroll;
}
