OK, here's another review of one of the Blackstone "Colours of Australia" inks produced by JustWrite.com.au - Daintree Green. For those of you who don't know, the Daintree is a rain forestsituated in north east Queensland - the largest tropical rainforest on the Australian continent. Which means that there's green - lots of green.
This is actually a pretty nice green ink. I think I'd expect a rainforest to be a bit darker - but maybe I'm just showing how long ago it was that I studied Geography, Ecology and, ummm, Botany. No matter, it's a nice mid-range green ink - and it even sheens a bit in a nice broad nib (on Tomoe River paper, anyway!).
Here's a scan (needs colour correction - the ink isn't quite as dark as this!):
And a photo (taken with my Sony smartphone) - I think this is a little more accurate:
