Are there any tools for finding which textures use which colors?

Technically, I think one could write a Lua script for that in SLADE. I still can't make head or tail of Lua scripting, though, so I'm not volunteering for the task. But looking at what's been exported, there are the functions for accessing entries, loading graphics and textures, and getting the palette index of individual pixels, so everything one who knows the language needs to write a script that will iterate over graphics, then iterate over their pixels, and keep count of how many pixels of each index are present in each.
