It's OK, can live without the color for now.

Probably misplaced intentions, but I want to want to understand TeX
properly first (TeXbook, etc.), before moving on to the higher level
of ConTeXt. But in the meantime, it would still be nice if good
looking documents could be produced, even if it requires much manual
tweaking. Started as an assembler programmer, then Forth, then C,
etc. Learn best from the bottom up:)

Have a good evening, and thank you for your time and attention.
