How to tweak the ccze color scheme a bit?

Question

System administration

I often look at the raw logs nginx helps out ccze with its coloring, but sometimes I need to distinguish a bot visitor from a living person, and in this I decided to do a little color filtering.
I noticed that bots use HTTP/1.1 and real users work overwhelmingly with HTTP/2.0
And I want (if possible) to highlight in color (for example, red) those who work via HTTP/1.1 and yellow (or otherwise) those who use HTTP /2.0

Where are some files that colorize the logs stored? :)
