Chromatography of Troublemaker Inks colour in question

I have a bottle of Troublemaker ink that is clearly labelled Milky Ocean on the cap, but writes more violet than blue on any paper I've tried. There is some doubt as to whether it's actually Milky Ocean, or actually something else in a mislabelled bottle. I showed the photos and scans to Gab at Troublemaker Inks, who then asked for chromatography of the ink I have.

Gab opined that it looks like Milky Ocean but couldn't be sure (that it wasn't a mislabelled bottle), and so is sending me a new bottle of Milky Ocean.
