A key has been added, written on Clairefontaine paper, with a number of different inks for reference.

Review
When I write a review, I first focus on color, and award an ink 0 to 100 based upon that alone, separate from other considerations. I then deduct points from the color score for defects (ie: lack of flow, creep, etc), to arrive at an overall score.
Color
This is a nice shade of blue/grey/black, with perhaps a touch of green. I do not see the overwhelming green notes that others describe. To me, this ink comes off as decidedly blue-black, with perhaps a hint of green. In my opinion, it combines the best of Diamine Blue-Black and Noodler's Legal Lapis, while forgoing the shortcomings of those two colors.
For some reason, this ink has a strong oceanic aura about it. Not necessarily ocean colored, but it conveys some feeling of the sea. An ideal color for a ship's log, perhaps.
Color Score = 86
Deductions
Noodler's Squetegue performed poorly on the water test. Perhaps this isn't an oceanic ink after all.
-5
Squetegue (or is it Squeteauge?) sounds more like a digestive ailment than a color.
-1 for goofy name
Overall Score = 80
