I want to edit the headings on my site to a different color, but can't find a way to do so within the ATO Body, text & Links section, nor in the Style Posts and Pages section.
They currently default to black.
I have tried putting code into 'insert CSS section', and that hasn't worked either.

This is the code I have used:
h1 {font-size: 30px; font-weight: normal; line-height: 120%; color: #b69121;}
h2 {font-size: 20px; font-weight: normal; line-height: 120%;}
h3 {font-size: 18px; font-weight: normal; line-height: 120%;}
h4 {font-size: 16px; line-height: 120%;}
h5 {font-size: 14px; line-height: 120%;}
h6 {font-size: 12px; line-height: 120%;}


How can I do this, and what code do I need? Is there something I am missing?

It looks like you added that code into the ato->Body, Text & Links->Body Style option not the ato->Add HTML/CSS Inserts->CSS Inserts option.

Thank you, I have sorted it out now.
Very useful to know about that option.
Appreciate your prompt response, also.
