Caveat: this year’s Inkvent appears to have elusive ink colours. I suggest reading my description of the inks and not going by the photos alone, and comparing my results with those of other reviewers.
The Diamine Inkvent calendar is an advent calendar with 24 tiny (12ml) bottles of fountain pen ink behind 24 doors, and a larger, 30ml, bottle of ink behind the 25th door. All the inks are limited edition, and, at the moment, only available through this calendar.
Day 6’s ink is Diamine Winter Spice. It’s a rich brown colour with a blue shimmer and a green sheen.
Here’s a Col-o-Ring swab of Diamine Winter Spice. It came out more yellowish in the photo than it looks like in reality – the Tomoe River sketch below is more true to colour. There’s a significant amount of blue shimmer and green sheen, especially with the music nib that I used to test out this ink.
I used a Sailor Pro Gear with a music nib to test Diamine Winter Spice, and it lays down a generous amount of ink.
I drew a Yayoi Kusama pumpkin to test Diamine Winter Spice out, and it shows the colour of the ink pretty well.
This was drawn on a Kanso Sasshi 3.5” x 5.5” Tomoe River Paper notebook (the notebooks I have were bought in 2016, and so they contain the old Tomoe River paper).
Finally, I wrote a page in my Midori Journal:
Diamine Winter Spice is the least favourite of the Inkvent 2021 inks that I’ve tested yet. Something about the combination of the brown with the green sheen and the blue shimmer makes the ink take on a sickly yellowish green tinge in certain lighting conditions. You can see it in the Col-o-Ring swab above. It’s another peculiar colour choice for the occasion, and not an ink that I see myself using in the future.
