The black pixels on these glasses, however, are actually dark gray (a byproduct of the type of screen used), which makes it obvious to the user that there is a screen and what its boundaries are. Is there a different “transparent” keyed color that our app can use to have a true transparent background
answer: It’s black, but if the brightness is turned all the way up you’ll still see the backlight. So it looks a little gray. So maybe can turn the brightness down.
