I get the same with '4.4.12(1)-release' too, but it doesn't seem related 
to Bash or the prompt. I can get it with just a printf, the colored part 
just needs to get wrapped by the end of line.

 printf "%100s $(tput setab 1)colored part$(tput sgr0) normal again\n"

If the screen scrolls, the background color on the last character gets 
copied to the next line. At least one way to work around that seems to 
be to clear the end of the line after the colored part ends, by putting 
"$(tput el)" after "$(tput sgr0)". You probably don't have anything to 
the right of the cursor at that point, so it'll only reset the color.
