Here are a few gifs of this one drying so you can see how it changes colors. It's really neat.

Also after cleaning up with a wet paper towel you can see it separated out into several different pleasant base colors.

In some ways it's similar to day 6 (Kilonova) but the color of the ink and the sheen are both different, with Kilonova being more even blurple and this is a dark blue base overall.

@jimp what a fun ink! Also I love that you took some video because it is so very cool to see it happen. Watching ink dry is so much more fun than the adage about paint drying!
