Unfortunately, that self-experiment has the problem of the subject (yourself) knowing which &quot;treatment&quot; you&#x27;re getting. I&#x27;m not sure how to double-blind something like this, though. It may require a study where we record subjects&#x27; sleep patters, make them use a screen at night, but don&#x27;t tell them that it&#x27;s the screen colors that are under experiment.
