Hello!
I made some ascii art for the guns a few years ago, but had to put that on hold for personal reasons. I'm back and ready to continue, but a problem I had then is cropping back up now.
Some colors, when exported to CDDA format using ctrl+j, are either different colors than what's in-game (some values of yellow in REXpaint become shades of brown in CDDA, for example), or are color combos that do not work at all (e.g. 'color_yellow_brown' throws an error and does not display. 'yellow with a brown background' does exist in-game, but it's called 'color_yellow_yellow' instead).
I looked through the REXpaint settings/config and could not find a way to change or add color tags for export. I looked through the directory, too, but didn't see any files I could open in notepad that had these color tags defined anywhere.
I'm motivated to get this working. I'll run a test later to see exactly which ones aren't working and what they should be instead. If I get a list of "bad color > good color" together, is this something that can be fixed?
