Fixed, sort of. This replacement green is too dark, but at least it’s out of the same slice of the color wheel.
This basically highlights the problem of color-picking with a woefully limited selection. Matching sprites designed with a palette of, what, 16 million colors? When you’ve got about 400 colors of thread to choose from? Not so much. There are 21 characters in this scene, and if I get through a single one of them without the color selection being a totally agonizing process, I will be amazed.
Edit: Third time’s the charm. Still not perfect, but I got it close enough that I’m done fucking with it.
