Ooo, nice blue. Now that I'm all about the blue may I ask what it is . . . ?
Umm, the color may not be reproduced very faithful here, I fear (you can tell that the lighting on the paper was pretty uneven). That said - it's Sailor Seiboku blue black pigment ink (in a brand new Pelikan Souverän M805 black blue silver with M nib).
