Welcome, ladies and gentlemen, to the Marilyn Darling Show—today I’m doing a re-review of Colorverse Rainy Day, which is a beautiful bluish, dusty, steel-blue kind of ink. I swatch it, I run a water resistance test (spoiler: it does not have very good water resistance), and then I do my toilet paper chromatographies—one with water and one with rubbing alcohol—so you can actually see what’s hiding in there. You get that green splotch in the middle, blue pushing out, and a little pink right along the edge, which is exactly why chromatography is so useful if you want to use ink for art washes and not just writing. Then I do what I always do: I put it through a ridiculous amount of paper, because paper is half the battle. On good paper—HP Premium 32lb, Copperplate graph pad, Oxford, CVS filler paper, Midori MD, Daiso Premium, Tomoe River 68gsm—Rainy Day looks gorgeous with shading and clean lines. On cheaper stuff (hello, “feathered like a chicken”), you’ll see feathering, micro-bleeding, and ghosting depending on the notebook. I also answer the “are inks waterbased?” question: fountain pen ink is mostly water-based with binders and dye/pigment, and alcohol-based would melt your plastics, so no thank you.
