Mixing PROMPT_COMMAND and PS1 is usually a bad idea. You can do this
using PS1 alone. Remember that all non-printing bytes must be enclosed
in literal \[ \] pairs.
red=$(tput setaf 1)
green=$(tput setaf 2)
reset=$(tput sgr0)
color=("$red" "$green")
PS1='\[${color[$?==0]}\...@\h:\w\$\[$reset\] '
(A bit confusing, using C-like evaluation where true is 1 and false is 0,
which is the opposite of bash... hence red being mapped to color[0]
instead of color[1]. But I hope you can understand it without further
explanation.)
