I was decorating and got annoyed that many of the Maxis paint colours didn't have many molding options... So I took a bunch of Maxis textures and did some Copy-Pasting:
There are nine colours: Awash in Blue, Powder Blue, Blue Collar, Simply Stunning, Lavender Blush, Pas Purple, Pink Slip, Beachy Keen, and Paystub Yellow. I've marked the walls in the preview that are made by Maxis, which I believe are all basegame except the 'Pas Purple' wall with white beadboard. All the other walls shown are included in the download, and should work with basegame only.
