Gravel is an ideal choice of landscaping material for anyone who wants a different look that will not break the budget. It can be decorative as well as utilitarian. Gravel is also easier to install compared to flagstones, marbles, granites and concrete slabs. When it comes to color choices, gravel has many options that you can use to complement any design style and color scheme.
Brown is an earth or neutral color that works well with any types of color scheme. It is one of the most commonly used gravel colors. Different shades of brown are available, which include tan, mocha, yellowish brown, orange-brown, golden-brown, reddish brown, bluish brown and grayish brown. Pea gravel, river rocks, river jacks, crushed stones, egg rocks, decomposed granite and pebbles all come in different shades of brown.
Gravel made of sandstones, produced through sedimentation consisting of quartz and feldspar, are common minerals you can find on the earth’s crust. Brown color comes from a blend of clear quartz with the dark amber feldspar content of the sand.
Sedimentary rocks made of pebbles, sand and combinations of quartz and plagioclase feldspars (albite, labradorite) create rocks that appear white to dark gray, sometimes black. They may show flashes of blue or green. Gray is a common color of river rocks, pea gravel and sand. It is also a common color for slate chips.
When pebbles and sand mix with calcite and dolomite, the result is usually white, off-white or creamy white. You will often find these minerals in limestone, dolostone and marble. The gravel looks shiny, especially under bright light, and often shaped like parallelograms. White is another color of pea gravel, egg rocks and marbles.
A color of gravel found predominantly in the southwestern United States is red. The iron oxide imparts the reddish tint ranging from pink to dark red, such as in the case of terracotta.
Crimson stone, also known as red dog, is a crimson-colored, fine, gravel-like aggregate typically used for pathways because of its unique red color and tendency to pack and firm when stepped on.
Hornblende minerals found on some sedimentary rocks used as gravel give a dark green to black color. This mineral gives gravel a flat, shiny face that is almost rectangular, which appears as long, thin needle-like crystals in rocks.
Actinolite and tremolite minerals contained in some sedimentary rocks usually appear in long, thin blades or needle-like crystals. Actinolite is dark green; tremolite is white to gray. They give a color that is predominantly greenish gray when combined with pebbles and sand to create gravel.
