The reason for this is that bash is counting the characters being output,
and assuming that each of them takes a space on the screen. However this
looks as if you are using ANSI escape sequences (or something based on
them), so that the \e[31;40m will actually take no space at all. To tell
bash that these take no space, put them inside a \[ \] pair, e.g.
PS1='\[\e[31;40m\]\u@\h:\[\e[32;40m\]\w\[\e[31;40m\]\$\[\e[0m\] '
This is described in the info page and the man page.
