I often use colored prompt for my user shell, so I edit the ~/.bashrc (copied from /etc/skel/.bashrc)
Since Hardy Heron, I've found a useful line, which seems to be put to avoid commenting or uncommenting numerous lines manually (line 33) :
# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
force_colored_prompt=yes

But the fact is that the following test doesn't correspond to the set variable (line 35) !!
if [ -n "$force_color_prompt" ]; then

We should change force_colored_prompt to force_color_prompt to define the variable, and everything is OK.
