I am attempting to use the posterdown package in RMarkdown (https://pythonawesome.com/use-rmarkdown-to-generate-pdf-conference-posters-via-html-or-latex/) to generate a nice PDF file. I noticed that the default template is generated as an HTML file once you install the package. Is there any way to set it to to generate as a PDF instead of an HTML file?

Additionally, is there a way to customise the default color (green) in the header and titles to an HTML color code of my choice?

Here is the default YAML

TIA!

You can control the color with the YAML or inline CSS, you will want to add knit: pagedown::chrome_print to your YAML to get print to PDF and retain the CSS code. I also changed my code to self_contained: TRUE out of habit. When I run the code below, I get changed posterdown header color, and it opens in my default PDF viewer as it's now a .PDF
