In this video I swatch and review six fountain pen inks that feel like autumn on paper—warm browns, punchy reds, moody greys, and those tree-inspired greens that just scream “journaling season.” I’m using a Cult Pens x Jacques Herbin mini glass dip pen on Clairefontaine 100gsm loose leaf, so you can really see the colour, shading, and overall vibe without a bunch of variables getting in the way. If you’re hunting for an everyday fall ink, or you just want a satisfying swatch session, this lineup covers a nice spread of brands and personalities. I go ink by ink—J. Herbin Lie de Thé, Pilot Iroshizuku Momiji, Troublemaker Autumn Rain Grey, Diamine x Cult Pens Murky Bucket, and Colorverse Methuselah Tree and Ginkgo Tree—then I compare them side by side so you can see which ones overlap and which ones fill a real gap in a collection. My goal here is practical: what looks good, what feels usable, and what kind of mood each ink brings to writing. By the end, you’ll have a clearer idea of which ink fits your autumn notes, letters, and daily pages.
