Present among one of the aggregates are a multitude of granules having at least one color and/or hue thereof not present among the granules of the other aggregate or aggregates. The strips are cut from the sheet and laminated one above the other so as to form at least two layers with the differently colored aggregates exposed to view. The difference in coloration creates a pleasing color contrast and accentuates the difference in elevation between the shingle layers.
