Filth is something on the ground that has negative beauty.
Filth is removed by colonists assigned to Cleaning. Only filth in the Home area will be cleaned, anything outside the area will be ignored. Note that a home area is automatically created when placing buildings or structures.
Certain unsightly objects, i.e. vomit, have one value when under a roof and a lower value when unroofed. This simulates the general disgust of seeing eyesores indoors versus encountering them outside. Some messes can be spread by pawns tracking through them and others can be washed away by rain.
The effect of filth on outdoors beauty is 30% of the effect indoors. Since all natural types of ground already have -1 beauty, without flooring, filth effectively has an additional -1.
