Today’s Diamine inkvent ink is Polar Glow, a deep blue with a subtle sheen – at least on this paper, in this lighting – but shows some shading, for me. From what I’ve read sheen seems to be quite dependant on the type of paper and lighting it’s viewed under. I think this one will definitely benefit from a broad or stub nib. This colour reminds me quite a bit of the FPN Noodler’s Van Gogh Starry Night Blue.
The paper being used is from the Pelikan Hub 2019 pad, with a slightly glossy finish to it. I notice the Candy Cane and Polar Glow also seem to have a tiny bit of feathering, but this is probably due to the use of the glass dip pen (the tip isn’t the smoothest, and it’s quite wet right after dipping – enough to cause some bleeding even with this heavier paper ).
