changing 33 to 30 will get you black. ANSI color escapes are on

Also, decent terminal emulators let users tweak the colors, and making
sure all main colors are readable on the default background would
probably be a good use of that ability.

This is a sore point with something I'm fighting with. Chinese
electronics makers are in the habit of publishing .pngs of their
products, with the most valuable info one needs to properly hook it
up, in a putrid yellow on a white background.
Would it be practical to put a filter in the path cups put things
headed to a printer thru, to change just that esc sequence to make
those boxes and their text content into something more readable.
For an example of such an unhelpful document, find a copy of
"MKS-Robin-Nano-V3.X-main.zip", unpack it, cd to Image-V3, and look at
"MKS_Robin_Nano_V3_PIN.png" on-screen or better yet print it.
Like this?

I can't help you with the printing.
I installed xli, works great, and is fast, but apparently has no output
redirection ability. I made several 0 length files trying.
gimp could probably do it, but I get lost in endless menu's.
imagemagick won't run from the cli, from the pulldowns, its file
selector is not controllable to navigate to the file. Trying to wade
thru home/src/MKS_nano_v3_main/hardware/Images-V3/ to that file was a
hopeless waste of time. Any attempt to scroll thru the presented very
busy file list with the mouse wheel was always interpreted as load the
first file. IOW its file selector is busted afaiac.
libreoffice loaded it, replaced the putrid yellow with black, and then
printed me a copy on photo paper, a copy I can actually read!
Mark it problem solved.
Thanks to all who responded.
Cheers, Gene Heskett.
