Abstract
According to one aspect of the present invention, there is provided a visual attenuation composition 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 includes an additive selected from the group consisting of a flocculent, a tackifier, a stabilizer, and combinations thereof. The visual attenuation composition may further include a liquid medium such as water to form a slurry suitable for spray application. The visual attenuation composition described herein can be combined with a soil treatment product to impart desirable color and colorfastness. Alternatively, the soil treatment product can be first applied to the landscape prior to the application of the visual attenuation composition.
