Greenish? Huh. That's... weird, as, in fact, one of the difference between the One and the Forma is that there is *no longer* a green LED involved in the mix
.
It definitely can't go as red as the One, I'll readily give you that, but greenish? Nope, can't see it, sorry :/.
EDIT: Here's how mine looks, as a comparison (since I assume you currently do have both a One and a Forma in front of you), with a few green & red items in the mix for comparison. As always, take this with a grain of salt, because taking meaningful pictures of an eInk screen is kind of hard ;p. Plus, middle of the day, bright sunlight, so I had to push everything to the max to actually pick up a tone, and not get it mangled by white balance adjustments.
EDITē: Don't worry about the veiny folds around the buttons. I may have dissolved the glue a bit after getting a bit heavy handed with isopropyl alcohol during a cleaning session ;p.
