[NTG-context] MKIV ansi/ansilog

Hi, I have been using the ansi and ansilog flags in the past and they work fine with lmtx, but do not seem to make a difference with luatex/mkiv. (There was a thread back in 2019: https://mailman.ntg.nl/pipermail/ntg-context/2019/095666.html) I am trying just a simple hello world: \starttext Hello World! \stoptext

From the latest lmtx install (2021.08.24 22:16) on an ubuntu 64bit live system:

These give the desired color output for lmtx context --ansi test.tex context --ansilog test.tex But with luatex, these make no difference in the stdout (no ansi colors) context --luatex --ansi test.tex context --luatex --ansilog test.tex Adam
