Has anyone used Noodler's Brittania's Blue Waves?

I'm really curious about this ink for it's permanent qualities, but for once I'm struggling to find examples of it online (with a couple of exceptions, both of which make it look dramatically different).

If anybody out there has used it, could you tell me:

Does it shade a lot?

Is it a true blue or does it end up looking very greenish (as so many lighter blues do)?

Also whether it's just dark enough to be legible when you have pages filled with it (I learned my lesson on the illegibility of bright inks when I bought Diamine Coral and China blue).

Better yet, I'd love to see some better examples of it if anyone could provide them.

Any help would be much appreciated!
