You are right that this is unlikely to cause problems, because users
are unlikely to put backslashes in version numbers. Henrik has pointed

palette is a property recorded in the graphics device* and therefore R will
create a new device (see dev.new()) if only the null device is open. Which
device is really up to your settings, so you could adjust your preferred device
depending on what you want it to be.

For many years, when my R process starts up I've been automatically
setting my preferred default plot colors, basically like so:
