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 14’s ink is Diamine Red Robin a standard orangey red.
The colour matches my vintage onion skin paper pad quite well.
Here’s a Col-o-Ring swab of Diamine Red Robin. There’s a lot of shading in this ink – from orange to red.
I used a Sailor Professional Gear Slim Graphite Lighthouse with an extra fine nib to try out this ink.
Of course I had to draw a red robin with Diamine Red Robin.
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:
While I don’t see myself buying a bottle of this ink, Diamine Red Robin is definitely a theme appropriate ink, and a nice bright ink in general. I’m personally just not a big fan of red inks, so this one isn’t for me.
