If you are like me, the recent addition of colorization to the Ruby 2.7+ IRB sessions is completely bothersome because its totally different colors than I use within VIM. I would rather have my Ruby console uncolored.
If you want to disable the IRB colorize feature simply add the following to your
# ~/.irbrc IRB.conf[:USE_COLORIZE] = false
If you do not add this to your
~/.irbrc you can instead simply pass
--nocolorize option on the command line
