Where is the SQL syntax Highlighter FAQ?

So I am newer to Hue.
C​ould someone please point me to a faq that tells me which colors stand for what type of value/instruction in Hue.
Meaning FROM, SELECT, etc are purple color, NULL is orange, something in quotes (literal) could be green (see attached screenshot).

I tried to answer this question myself by going to the Hue website. I found this: https://gethue.com/how-to-improve-or-add-your-own-sql-syntax-highlighter/
Which tells me the highlighting is powered by ACE but not a link to some simple page that tells me what is what.

If anyone could point to a page that tells me what colors stand for what that would be very helpful.
