    Abstract: Patterned fibrous substrates having a plurality of individual fibers, a first region, and a second region are provided. The patterned fibrous substrates have a plurality of individual fibers of the first region having a first diameter and a plurality of individual fibers of the second region have a second diameter, wherein the first diameter is less than the second diameter. The individual fibers of the first region and the individual fibers of the second region are substantially free of bonds, other than primary bonds. The first region has a first C.I.E. L* score, and the second region has a second C.I.E. L* score, according to the Color Test Method. The first C.I.E. L* score is different than the second C.I.E. L* score.
