2750. New Ink: Kaweco Midnight Blue
I got this ink for half price (it became affordable to me), and it's the colour I don't have yet; since it looks different from Platinum Pigment Blue.

I actually like the kraft paper box, feels nice!
Ink test took me a while as I tried to register how the colour looks in my brain haha:

It feels like a muted blue, and sometimes grey-like. But it also looks really blue sometimes. I'm confused actually hahah.
One surprising thing: I learnt that this ink has medium waterproof tolerance. That's a nice surprise!
