Some info here on colour https://www.outdoorking-forum.com.au/forum/ubbthreads.php/topics/78150/scott-bonnar-colour-names.html
This part of the forum doesn't like links working so you can copy and paste the link into address bar or highlight and open in new tab.
I'm not sure if you will find anything off the shelf that is a good match but have heard most people take a sample of the colour they want to a paint shop and get the paint colour mixed correctly for their project ,this is usually the more expensive option.
