This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
People bug fix their pages until the validator gives green. Tentatively passed also gives green, while there's still room for improvement. People often stop reading when they see green. Often they don't even look at the page at all, but only at the favicon in the browsertab being red or green. I propose a color between yellow and orange (as traffic lights have different colors around the world).
