How to change font color in one template section only.

[MikeW1]

Using Dawn Theme and would like to change the text color that appears only on the homepage with the hero image. I have the template section.

Try a custom css setting

https://help.shopify.com/en/manual/online-store/themes/theme-structure/extend/add-css 

So a link tag <a>, a  button , or a paragraph etc

a , button, p {
 color:red;
} 

 though it could just as easily be heading tags

h2,h3,h4,h5,h6 {
 color:red;
} 

You might need to inspect the theme to figure out the specific elements are that your trying to target.

To find what the elements are you can either in chrome browser press ctrl+shift+c to open devtools element inspector , or find a browser extension/plugin that helps identify elements on a page for use with CSS.

Thanks that has led me to look into custom CSS rather than alter the theme.css. 

To be clear, I am looking to alter the font color on just the heading on the homepage of dawn theme. I think it is listed as

<h2 class="banner__heading h0" >

<div class="banner__text body" >

[PaulNewton]

the CSS selectors for those are

h2.banner__heading  and div.banner__text
