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.
