Hello my fellow fountain pen lovers. I love rich, vivid, deeply saturated fountain pen inks, particularly those that shade. My favorite inks are Colorverse Supernova, which shades gorgeously from a rich blue to a lighter blue, and Diamine November Rain, which in my green-and-black Pelikan M600, shades (you guessed it) from green to black beautifully.

For my Lamy 2000, which I just bought to be my daily-use pocket pen, I’m searching for a waterproof blue ink. But my problem is that almost all the waterproof inks I’ve tried are cloudy, unsaturated and unsatisfying. I just bought a bottle of Sailor Seiboku. To me, this is a pale, cloudy ink, the opposite of the rich, saturated colors I love. And iron gall inks are generally dry writers, so that’s a nonstarter. Got to have a wet ink.

What’s the perfect, saturated, wet, waterproof blue ink? Thanks in advance for your advice!
