The variegated shingle comprises a shingle layer having front and rear surfaces, the front surface including a butt (20) portion and a headlap portion (18). The shingle layer contains granules on the front surface forming a plurality of horizontal striations (26, 28, 30) providing gradations having color values ranging from light to dark extending between a leading edge (22) of the butt portion and an upper portion (24) thereof. The striations include an upper striation (26) along the upper portion, a lower striation (28) closer to the leading edge (22), and an intermediate striation (30) between the upper and lower striations (26, 28). The upper striation (26) is darker in color value than the lower striation (28), whereas the intermediate striation (30) is no darker in color value than the upper striation (26) and no lighter in color value than the lower striation (28). The color values of at least one of the upper, lower, and intermediate striations (26, 28, 30) vary across the granule layer. |
