Background for word

It's a new editor feature: see the release notes:

https://dailies.rstudio.com/version/2022.12.0+353.pro20/
? Code editor can show previews of color in strings (R named colors e.g. ?tomato3? or of the forms ?#rgb?, ?#rrggbb?, ?#rrggbbaa?) when Options > Code > Display > [ ] enable preview of named and hexadecimal colors is checked.

You can turn it off in the global preferences if it bothers you.
Tools > Global Options ... > Code > Display ... there is the checkbox mentioned above

I like it, it's really useful to set up colour ramps. 


Cheers,
Boris
