An explanation of my inks!
At the request of @exnihilo-comic
I generally use fountain pen inks with my dip pen. Here are some of the most common inks I use:
Lamy Azurite: Probably my current favorite go-to ink. It's an indigo-purple ink with a high gold sheen.
Example here: RagingTurmoil
Diamine Oxblood: If you ever want blood-red ink, this is it. This is such a well-behaved ink, it's got such a saturated colour that looks great in both fountain pens and dip pens!
Noodler's Black: It's a basic black ink. Not the most saturated, and can appear grey if your nib is running low. But it's solvent proof and is phenomenal on cheap paper. [One side note- I've been fooled by "waterproof" inks before, and so I tested this one. I gave a 30sec dry time, then painted on water, or alcohol, or acetone, or ammonia. This ink remained perfectly legible in water, alcohol, and acetone. It had some smearing in ammonia. So yeah, I believe them when they say it's bulletproof.]

Noodler's Purple Mountain Majesties: This is a purple, but it's more of a magenta-purple, with decidedly pink notes. This ink is not bulletproof, but it is fun.

Van Dieman's Blue Ringed Octopus: It's a high saturation blue ink with a HIGH pink sheen. It's delightful, another favorite of mine.
Example here: YourGoblinIsValid
Van Dieman's Kingfisher: This is a shimmer ink, which means it contains particulates that make it glitter. Technically it markets itself as a fountain pen ink, but I wouldn't put it in a fountain pen, you're just asking for a clogged nib. Perfectly good for dip pens though!
Example here: SufficientlyAdvancedWitchcraft
The green ink I use most frequently (my Magnus Archives green) is actually a custom mix of dip pen inks of yellow-green and a forest green! I don't even know if it's a brand name, just some random ink off amazon. I know, not super helpful. I have a few other colours from this set that I have mixed-and-matched with less than stellar results. This is definitely my favorite of my no-brand calligraphy ink.
Example here: I'veBeenWatchingYou
Dr. Ph. Martin's Copper Plate Gold: This is my illumination ink! Shimmery, iridescent, shiny gold. I wasn't brave enough for gold leaf, so I'm using gold ink instead.
Example here: DIE
In this example, the other colour is Diamine Oxblood!
And one more thoughts on inks: you can absolutely use fountain pen inks with dip pens, though the ink may be a little thin. You should not use calligraphy inks in fountain pens, they're too thick and will clog your nibs.
Hope that helps! Thank you for asking!
