I decided to share two set of custom palettes I made for Touhou 12.3 based on the two main fighting game series by Arc System Works: BlazBlue and Guilty Gear.

Feel free to comment on how to make those palettes closer to the sources they're based on!
The BlazBlue palette set was actually made to cope with a certain...controversy regarding the newest game of that series that resulted in me abandoning it. I won't go into detail to avoid straying off topic.
The Guilty Gear set is based on characters who appeared in the base release of GGXX, which means there's no palettes based on updates to that or the Xrd subseries.
Yes, I know that Yuyuko's palette on this set is similar to her actual third palette, but mine has a few minute differences.
To be honest, I wish there was a palette editor for ULiL... I would love to make some palettes for that game.
