<p>Deleting a post does <em>not</em> make it become "faded". </p>

<p>Deleting a post hides the post from all users with &lt;10K reputation (except for the question owner himself and moderators). Those who are able to see the deleted posts (owner, moderators, and 10K + users) will see the deleted post appear with a <em>pink</em> background, as opposed to the usual <em>white</em> background, indicating that the post is deleted. </p>

<p>Faded posts are those post with low scores. See <a href="http://meta.stackexchange.com/a/142320/155238">this discussion on Meta.SO</a>. </p>
