Yes, TS4 needed more swatches for many things, however, didn't Maxis try selling recolors to the mobile gamers? It didn't go over too well, and frankly I won't pay for a recolor when with a little time anyone can learn to recolor these games or just download one for free without having to also download or install ten purples, ten shades of lime green etc. But I understand your point, that yes, Maxis never setup this game for all parts of an object to accept a recolor. That is the whole problem actually because if they had it would be so much easier for players to want to do this for themselves.
