I created a sample environment.
1. Use the attached fixes_diffcolor.py as fixes.py, or copy the fix from it to your fixes.py.
2. https://hu.wikipedia.org/wiki/F%C3%A1jl:Uncoloured_replace_2in1.png will emphasize two colouring errors in their original enviromnent (one ó/ő and one é/á). I copied the original text to my test subpage.
3. Use the command
replace.py -lang:hu -page:user:BinBot/semmi -fix:1970-as
The bot will want to make 3 corrections, the above given 2 of them uncoloured. (You don't have to actually press y, the test page is good if it is wrong. :-))

Could you provide a test command line in order we could check it for core (and compat as well)
