# qfile `which unbuffer`
app-misc/unbuffer (/usr/bin/unbuffer)

unbuffer won't help you there anyway. That only changes when stuff is
written to the pipe.

You're actually looking for:


   --color < y | n >
  Enable  or  disable  color  output.   This  option will override
  NOCOLOR (see make.conf(5)) and may also be used to  force  color
  output  when  stdout is not a tty (by default, color is disabled
  unless stdout is a tty).

BTW: if you don't want that colorized output in the log, add

app-text/ansifilter (/usr/bin/ansifilter)

for reading the log.

HTH,

  From "man emerge"

   --color < y | n >
  Enable  or  disable  color  output.   This  option will override
  NOCOLOR (see make.conf(5)) and may also be used to  force  color

  So you'd want...

/usr/bin/emerge --color y --ask --update --deep --newuse --tree --verbose 
@world | tee --append nom.txt

  Insert "--color y" into the command.
