Abstract
According to one aspect of the present invention, a visual attenuation composition is provided to be applicable to a landscape to visually attenuate or camouflage the landscape to approximate color characteristics of the surrounding terrain. The visual attenuation composition includes a colorant selected from the group consisting of a pigment, a dye, and combinations thereof, and optionally an additive selected from the group consisting of a flocculent, a tackifier, a stabilizer, and combinations thereof. The visual attenuation composition can be formulated to impart colorfastness as applied for a period of up to 6 weeks or longer. The visual attenuation composition described herein can be premixed with an erosion control medium or a blended mulch product described herein to impart desirable color and colorfastness. Alternatively, the erosion control medium and the blended mulch product can be applied to a ground surface prior to coloring and or color reinforcement with the visual attenuation composition.
