Which <palette tint=""/> values correspond to which colors of monsters???? Does anybody have a table or a chart or something for this?
You can't. It's a hue shift. Black/white aren't on the list for adding or removing, and most of the statue sprite is comprised of varying shades of each. You'll need to edit the base.pngs and define a new monster.
Get colour wheel. Palette tint value is the amount of degrees by which you rotate it, with every affected colour becoming one that is in its place after the rotation is done.
