You've made this comment more than once in this thread. Have you correctly understood that the policy is only the green parts in that link and not the red parts?
Fixed those replies, thanks for flagging.
OTOH, do you think a diagonal-lined-background on the removed side would work better? like striped light and dark red, vs solid green. I don't think I've seen anything do different than "red/green background of similar lightness", which is sorta surprising...
