Now trying the #Catpuccin color scheme. First impressions:
1. Even the darkest of the four shades is not too dark for me to open a dark-mode text editor besides a white-background web page.
2. It is consistently available for #RStudio, #Neovim, #MicroTextEditor and #Ptyxis, and hundreds of other applications
3. Colors for code comments are subdued as usual. At least I can read them without cranking screen brightness to full, but ideally I'd like more contrast.
