What Hacker News says

Emacs' 'Rainbow Identifiers' does that. I like it.

In Tree Sitter and the Complications of Parsing LanguagesI'm on exactly the opposite end of the spectrum (and no one else seems to be supporting the full opposite position, so I may as well). I use use emacs with rainbow-identifiers-mode[1] enabled, which gives every variable a different color. I can't say for certain that it makes me more productive. I just turned enabled it on a lark when I installed spacemacs. But it's fun, and looking at code without it on seems somehow boring now. I'm definitely more comfortable with it on than with it off.
