Not op, but in my case a lifetime of colourblindness has desensitised me to colour as an indicator.
I have my editor configured with zero highlighting for keywords and syntactic elements. Admittedly, I have compilation/lint/syntax/type check errors set to invert the erroneous block, black background white text.
Syntax and keyword highlighting is just noise given I’ve been trained by decades of colourblind unfriendly interfaces
that's a very good reason to not use syntax highlighting. If that is what the other guys are dealing with, I withdraw my critique but I don't get the impression that is the case
