A collection of dry river rocks may contain a wide range of light and dark colors, such as shades of gray, red, brown, white and beige. Unfortunately, some mixed-color batches make a landscape too visually busy. Mixed-color river rocks may clash with your home's color as well. For example, a pathway made of multicolor river rocks is a risky choice for owners of homes painted lavender. Imagine how mixed river rock colors will look on your landscape when they're dry and wet before making a purchase.
When light river rocks rest near green grass, they add an unforgettable amount of visual contrast to a landscape. Pay close attention to how you use light-colored river rocks. If you already have a focal area on your landscape, this type of decorative river rock may overwhelm it. Light-colored decorative river rocks look bright in direct sunlight and become less pronounced in shaded areas. However, proper lighting makes this type of rock beautiful after sundown.
Dark river rocks add formal elegance to a landscape. Just as food looks more attractive on a black plate, colorful flowers and dark river rocks create high-contrast, visually appealing scenes. Unfortunately, dark river rocks attract and hold a lot of heat. Dark river rocks, sunny climates and dainty flowers are not a good combination. Residents of sunny climates should protect their lawns from potential burns along dark river rock pathways.
