Well, I initially misread the label as ‘Mullet’ when I first opened the flap, so that should tell you how the morning started. Mulled Wine is a bit of a surprise right after yesterday’s Noel – the colour similarity is noticeable. (Don’t get me wrong, I like the colour, but…. a feeling of deja-vu for sure.)
That being said – from what I can see: it is a wetter ink, not quite as saturated, shading is not as subtly gradated, and a bit cooler than Noel. Samples done on three types of paper (Pelikan 2019 Hub pad, 32lb HP Premium Laser, Staples Bagesse) for comparison on how it handles. You could definitely confuse which ink you had loaded in your pen. I imagine your mileage will vary of course, depending on pen and paper.
