Font Styling

I'm looking to add an additional font to my client's site to give more styling options. The font I want to use is already in SS but just wonder if anyone has any suggestions on best practices to add an h4 or if better to use markdown block or even make h2 a different font than h1 & h3. Thanks in advance. 

You can use Code Block

<h2 style="font-family:futura-pt;">Text heading 2</h2>

or you can add this code to Home > Design > Custom CSS to apply h2 on entire site

h2 {
	font-family: futura-pt;
	font-size: 2em;
	line-height: 1.5em;
}

you can add more attribute

I want to use a new font that's been created for me. Do I just install the font in my windows/font files and then create the coding as above to point to it/upload it?

Or do I have to upload it to SS somehow first?

I also want to use a new colour palette for my new font. I've looked for instructions on that but can't find them - can someone point me in the right direction please?

It would be better to upload it then host it off your site.

Upload to your site: https://support.squarespace.com/hc/en-us/articles/205813928-Uploading-and-managing-files

then add this to Home > Design > Custom CSS

@font-face {
	src: url(paste font file url here);
	font-family: tuan;
}
h1, h2, h3, h4 {
	font-family: tuan;
}
