ACCEPTED ANSWER

Score 54

Use the --human parameter to view colored dmesg output in a less-like environment.

dmesg --human --color=always

Or use the short version:

dmesg -H

Alternatively, use the following command to achieve similar results.

dmesg --color=always | less -R

Many other utilities that produce colored output (ls, grep, etc.) have a similar --color=always option.

ANSWER 2

Score 2

A generic command to preserve coloration independent of the program providing the output is the unbuffer command (which is part of the expect package).

Usage:

unbuffer dmesg | less -R

ANSWER 3

Score 1

Yes, it works nice.

for tree: tree -C | less -r
for ls: ls -lA --color=always | less -r
for pytest: py.test --color=yes | less -r
