our keyboard has a 'purple' (it's really more pink) backlight that is made up of a red led and a blue led and it has caused me to realize that our glasses have pretty severe chromatic dispersion when angled, to the point that we can actually completely resolve the logo separately in red and blue from across the room just by tilting our head down
@starkatt like, we've noticed that light from blue LEDs seen from across the room doesn't seem to line up with the actual LED itself, it seems to be coming from below them
