Delete the Paint rule.

Add to the list on the Items rule:

* Paint. Cost $10. Paint must be specified in the Items field as ((Color)) Paint, where ((Color)) is one of the color codes of the Homeland Square of the Player purchasing the Paint at the time of that purchase. A unit of Paint may be used by a Player to change one of the Color Codes in the Square e is on to the color of the Paint. That Square has then been Painted that color. Note: Color coding restrictions detailed in rule 14 - World, and its subsections still apply. For example:
** Painting a Gray Square with XXX Paint will work this way: The Gray color code becomes XXX. Then, as the Square is still listed by name in some rule, it will gain the Gray color code again - and will be now both XXX and Gray.
** Painting any Square with Blue Paint will make that Square a Warp one.
** Etc.
