That's a very good point.

Latter hardware revisions use darker markings that are fine in reasonable lighting conditions but in low light they are still comparatively hard to make out.

Thanks for pointing out the optical illusion effects. I always use my calcs in good light since tbe V'Ger and Pioneers are LCDs. So, lighting is not too much a choreography problem. But, since, like the (gasp) TI N-Spire CAS, the Prime has backlight settings, I would make a point of using the Prime in a well lit area.

Thanks
