Perhaps, instead of doing it to match all of the palettes, which is, as stated, by far too much work, we could do base colors (like our valkyrie helms) and recolor it to the same colors the valk helms are offered in? Also, maybe we could change the valk exchanger (or whatever the NPCs name is) to something more universal, such as Color Exchanger. This way, we would have variety with at most, a couple weeks worth of work, possibly more (I dont wanna say anything certain about the length, never worked with sprites before. :\)
