Day 21 of the diamine inkvent is another extreme sheening ink called Cosmic Glow. It’s a nice dark blue color with a purplish red sheen, depending on the light. I really like this one. I did an edit the pictures a little to try and get a closer match to what I was seeing in person.
I also played with some mixed media paper by putting down a couple drops of the color and smooching it with a plastic sandwich baggie
Also as a bonus, here are the past 7 days of inks on 150gsm ivory white paper
