Your term looks rather low contrast with that rather bright dark greenish background... I use 'grey5' ;) You can also adjust the colours see 'man 5 color.map' and /etc/portage/color.map. And/or even patch emerge's output routines (I think there's some stuff that has no variable in color.map, and which is hard to read on grey5). I use this: ==== /etc/portage/patches/sys-apps/portage/portage_output_colors-2.3.44.patch ==== diff -x '*~' -purN a/lib/portage/output.py b/lib/portage/output.py --- a/lib/portage/output.py 2017-12-16 01:48:01.000000000 +0100 +++ b/lib/portage/output.py 2017-12-16 05:54:28.701929379 +0100 @@ -100,8 +115,8 @@ codes["darkgreen"] = codes["0x00AA00"] codes["yellow"] = codes["0xFFFF55"] codes["brown"] = codes["0xAA5500"] -codes["blue"] = codes["0x5555FF"] -codes["darkblue"] = codes["0x0000AA"] +codes["blue"] = esc_seq + "36;1m" # codes["0x5555FF"] +codes["darkblue"] = esc_seq + "36m" # codes["0x0000AA"] codes["fuchsia"] = codes["0xFF55FF"] codes["purple"] = codes["0xAA00AA"] ==== >man pages in color are the other most important problem right now.

By default, man uses less -s. This option overrides the $MANPAGER environment variable, which in turn overrides the $PAGER environment variable.

Oh, and have a look at your terminal options. E.g. use 'xterm -cm' instead of 'xterm'... (or set the according Xresource) and all you get is black & white ;) HTH, -dnh -- # Mmm, yesssss. cookies my preciousssss! Mmm, yes downloads it # is!
