> Eye-Searing-255
Lol....this. If your primary workstation OS is Windows then I recommend grabbing a copy of MobaXTerm. It has the ability to override and tame the "Eye-Searing-255" beast with its own themes (Solarized Dark and Light, Pastels etc). No more "oh-my-god-my-eyes" when you open up "ooby-doofer.pl" in vim.
Low-hanging fruit is the braindead R/G/B/Cyan/Magenta/Yellow used by some terminals in response to ANSI escape codes: https://sdkmvx.files.wordpress.com/2008/08/ansi-colors.png
In my mind, there's three types of colouring: None, Designed-By-Human, and the aforementioned Eye-Searing-255 (which should really be killed off or at least not be the default for anything used seriously). It's disgusting to open source code using vi or similar and have it presented in Eye-Searing-255.
