The styles that have a recolorable accessory can be found in the hat section of the catalog.
They appear in the everyday, formalwear, sleepwear, swimwear, athletic, career, outerwear, and naked categories and are set to valid for maternity and valid for random. These hairstyles are for teen, young adult, adult, and elder females. As I mentioned in the first upload, I dislike using high poly CC hair meshes on all the random sims that populate my worlds, so I went through several of EA's store and expansion pack hairstyles and removed the clunky accessories, redid the textures, and made a few other fix-up type changes (such as resizing them, correcting bad mapping, fixing bone assignments, and so on).
