Arrrggh - I just spent far too long trying to find this 'green'!
Slight tangent, if we're talking about calibrating monitors. Mine has two settings for 'colour temperature', 9300k and 6500k. Which is the 'correct' one? I use 9300k because otherwise white looks a funny colour.
On my brightness settings, white is not really as pure white as it could be, otherwise it burns my eyes... which is probably why the dark green here looks black!
