A process is provided for forming a building product having a color variation representative of a "natural" building material. The process includes feeding a first amount of a first material and a second amount of a second material to an extruder, mixing at least a portion of the first amount with at least a portion of the second amount in the extruder to form a third material, and extruding the third material from the extruder to form a product from the extruded third material. The formed product has a color variation representative of a "natural" building material such as ceramic, clay, wood, slate, stone, brick, concrete, metal, etc. The first material is formed of a first fiber, a first resin, and a first colorant. The second material is formed of a second fiber, a second resin, and a second colorant, wherein the second colorant is different than the first colorant.
