Claim:
1. A method of forming a varied pattern on an surface of a substrate, the surface including a first portion, a second portion, a third portion, and a fourth portion, wherein the first portion abuts the second portion at a surface boundary, the method comprising: applying a first mask on the first portion and the second portion, leaving the third portion and the fourth portion exposed; exposing the third portion and the fourth portion to a first texturing process; removing the first mask; applying a second mask on the second portion and the third portion, leaving the first portion and the fourth portion exposed; imparting a first surface texture to the first portion and a fourth surface texture to the fourth portion by exposing the first portion and the fourth portion to a second texturing process; removing the second mask, thereby revealing a second surface texture of the second portion and a third surface texture of the third portion, wherein the first, second, third and fourth surface textures are different from each other; forming a first anodized layer that overlays the first portion, the first anodized layer characterized as having a first abrasion resistance; and forming a second anodized layer that overlays the second portion, the second anodized layer characterized as having a second abrasion resistance different from the first abrasion resistance, wherein the first anodized layer abuts the second anodized layer at a layer boundary that coincides with the surface boundary.
