Thanks for the trivia, although your comment on displays is a bit misleading: >I first viewed it on a Linux desktop; on a Mac laptop with Retina display it looks much better though somewhat “light”

There's nothing special about Apple displays that makes them "retina", it's just a (marketing) term they use that denotes a standard for pixel density at a specific distance away from the screen. The point I'm trying to make here is you could have just as easily had a "retina" display on your linux machine, if not better.
