In our new Modern Sites we can change the themes easily from a list of default ones. As shown below.
Now as per my assumptions the names of these default themes are Red, Blue, Orange etc.
I am provisioning new Modern Sites using PnP code. I have seen many articles mentioning easy to create a custom theme and set them. (PS cmd: Set-PnPWebTheme OR c#: Tenant.SetWebTheme)
But how can we set one of the default ones? Like while provisioning a modern site I want to set "Red" as a default theme for my site collection.
