Changed the forest palettes so one mid-brightness color is no longer shared with the background; it made it impossible to do any palette-shifts which did changes to luminosity.  Changingthe slope of the 2nd-derivative of a given color-ramp's luminosity, within a palette-shift, seems like it can only be done to flat textures, and not to illustrated objects with baked-in shading, since altering the shading changes the apparent surface normal to something that looks broken/glitched (i.e. suggesting an impossible shape).
