Attached below is an image of a writing sample with PR American Blue, and below that, the review proper. Regarding the image, "lorem ipsum" is a nonsense language used by printers to showcase a font/color (ie: it takes focus away from content and puts it on aesthetics). The water test was performed by submerging and agitating a sample swatch of the given ink in reverse osmosis water for thirty seconds, then letting it drip dry.
A key has been added, written on Clairefontaine paper, with a number of different inks for reference.
Standard Disclaimer: Image provided only to give a general sense of the color. The vibrance and nuance are typically lost when an ink is digitized.

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
PR American Blue is a nice, vibrant blue. Reminds me of a darker Ottoman Azure. Doesn’t really offer anything new or exciting, and there are better blues to be had elsewhere.
Color Score = 85
Deductions
American Blue is not water friendly, but is still [somewhat] legible after having been dunked.
-3
Overall Score = 82
