I tested it with

    export PS1='[\h:\w\] '
and
    export 
PS1='\[ESC[1;33m[ESC[31m\uESC[32m@ESC[34m\hESC[35m:ESC[36m\wESC[33m]ESC[0m '

abd both I get:

    [michelle.konzack@tp570:~] cd /tmp
    [michelle.konzack@tp570:~] mkdir /tmp/chaos\\ ; cd /tmp/chaos\\
    [michelle.konzack@tp570:/tmp/chaos\] 

It seems to be an non-escaped coloring sequence
