For a long time, when I type man anything on my Mac, both the manpage header fonts and the background was black, so I had to use my mouse to highlight the manpage output to read it. It was really annoying.
The problem was the same both locally or using the terminal and going ssh somewhere.

mkzftree
MKZFTREE(1) H. Peter Anvin MKZFTREE(1)
NAME
mkzftree - Create a zisofs/RockRidge compressed file tree
SYNOPSIS
mkzftree [OPTIONS]... INPUT OUTPUT
DESCRIPTION
Takes an input file tree (INPUT) and create a corresponding compressed file tree (OUTPUT) that can be used with an appropriately patched
mkisofs(8) to create a transparent-compression ISO 9660/Rock Ridge filesystem using the "ZF" compression records.
OPTIONS
-f, --force
Always compress all files, even if they get larger when compressed.
-z level, --level level
Select compression level (1-9, default is 9). Lower compression levels are faster, but typically result in larger output.
-u, --uncompress
Uncompress an already compressed tree. This can be used to read a compressed filesystem on a system which cannot read them
natively.
-p parallelism, --parallelism parallelism
Compress in parallel. The parallelism value indicates how many compression threads are allowed to run.
-x, --one-filesystem
Do not cross filesystem boundaries, but create directory stubs at mount points.
-X, --strict-one-filesystem
Do not cross filesystem boundaries, and do not create directory stubs at mount points.
-C path, --crib-path path
Steal ("crib") files from another directory if it looks (based on name, size, type and modification time) like they match entries in
the new filesystem. The "crib tree" is usually the compressed version of an older version of the same workload; this thus allows
for "incremental rebuilds" of a compressed filesystem tree. The files are hardlinked from the crib tree to the output tree, so if
it is desirable to keep the link count correct the crib path should be deleted before running mkisofs. The crib tree must be on the
same filesystem as the output tree.
-l, --local
Do not recurse into subdirectories, but create the directories themselves.
-L, --strict-local
Do not recurse into subdirectories, and do not create directories.
-F, --file
Indicates that INPUT may not necessarily be a directory; this allows operation on a single file. Note especially that if -F is
specified, and INPUT is a symlink, the symlink itself will be copied rather than whatever it happens to point to.
-s, --sloppy
Treat file modes, times and ownership data as less than precious information and don't abort if they cannot be set. This may be
useful if running mkisofs on an input tree you do not own.
-v, --verbose
Increase the program verbosity.
-V value, --verbosity value
Set the program verbosity to value.
-q, --quiet
Issue no messages whatsoever, including error messages. This is the same as specifying -V 0.
-h, --help
Display a brief help message.
-w, --version
Display the release version.
BUGS
Long options (beginning with --) may not work on all systems. See the message printed out by mkzftree -h to see if this applies to your
system.
Inode change times (ctimes) are not copied. This is a system limitation and applies to all file copy programs.
If using the parallel option (-z) the access times (atimes) on directories may or may not be copied. If it is important that the atimes on
directories are copied exactly, avoid using -z.
