Where do I have to take a look at in the system to colorize the man pages?

The man pages are viewed with less, so I tried adding the following lines to my .bashrc to change the colors: (Which works fine, btw.)

 #
 #   L E S S   C O L O R S   F O R   M A N   P A G E S
 #

 # CHANGE FIRST NUMBER PAIR FOR COMMAND AND FLAG COLOR
 # currently 0;33 a.k.a. brown, which is dark yellow for me 
    export LESS_TERMCAP_md=$'\E[0;33;5;74m'  # begin bold

 # CHANGE FIRST NUMBER PAIR FOR PARAMETER COLOR
 # currently 0;36 a.k.a. cyan
    export LESS_TERMCAP_us=$'\E[0;36;5;146m' # begin underline

 # don't change anything here
    export LESS_TERMCAP_mb=$'\E[1;31m'       # begin blinking
    export LESS_TERMCAP_me=$'\E[0m'           # end mode
    export LESS_TERMCAP_se=$'\E[0m'           # end standout-mode
    export LESS_TERMCAP_so=$'\E[38;5;246m'    # begin standout-mode - info box
    export LESS_TERMCAP_ue=$'\E[0m'           # end underline

To my shame I have to admit that I did not find out what the second number pair meant, i.e. the 5;74 and the 5;146.

Can someone clarify that further?

What is it with the close votes? I have known the wikipedia link before and still i have no idea what the order of the sequence means. Trial and error and setting different values did not help me at all. A simple "go RTFM" does not help me here. –  sjas Jul 21 '12 at 23:12
    
You gotta be kidding me... this is just great! Where is this stuff documented? I looked in the BASH and LESS man pages but could not find the LESS_TERMCAP string. –  ysap Jan 23 '13 at 8:21
    
OK, found this for starters: unix.stackexchange.com/questions/119/colors-in-man-pages –  ysap Jan 23 '13 at 8:23
    
This: "for name [ [ in [ word ... ] ] ; ] do list ; done" makes more sense now, in color... 8-) –  ysap Jan 23 '13 at 8:28
    
@ysap : Haven't seen that links, and cannot remember where I found this. Put this here for documentation purposes and asked about the escape sequences in the process. :) –  sjas Jan 23 '13 at 9:18

"\e[...m" is the SGR CSI code. The Wikipedia page on "ANSI escape code", "CSI codes" section describes them.

With the help of http://invisible-island.net/xterm/ctlseqs/ctlseqs.html and the wikipedia link I came to the conclusion that 5 means 5 Blink: Slow less than 150 per minute.

The last numbers sound like this:

 If 88- or 256-color support is compiled, the following apply. 
 P s = 3 8 ; 5 ; P s → Set foreground color to the second P s . 
 P s = 4 8 ; 5 ; P s → Set background color to the second P s .

Also it seems that the amount of numbers is not important, just their chronological order.

Not exactly a bash solution, but still relevant, use:

PAGER=~/bin/vimpager

and drop this into ~/bin: https://github.com/rkitover/vimpager
