I'm not sure whether you are asking how scientists describe soil colors, or what causes soil to be a particular color.
Scientists describe soil colors by comparing the soil with standard soil color chips. The most widely used maker of color chips for soils in the United States is Munsell. Scientists carry a small book of Munsell color chips into the field with them when they are describing soil features.
Most soils have the colors that they have because of microscopic coatings on mineral soil particles. Typically, soil minerals are white or gray if they are not coated.
Red and yellow colors come from different types of iron oxide coatings. Black and dark brown colors usually come from organic matter coatings, but may also come from manganese oxide coatings. Organic matter and oxides can also mix to produce reddish and yellowish brown soils.
When soils are gray or white, they are lacking coatings. This can indicate wet conditions, or that organic acids have stripped the coatings from the soil particles. When soils are mottled, with gray, white, yellow and red colors all mixed together, it is a sign that the soil is sometimes wet and sometimes dry.

What gives soil color?
Soil color is primarily determined by its mineral content and organic matter. For example, the presence of iron can give soil a red or yellow color, while high organic matter content can make soil darker in color. Soil color can also be influenced by environmental factors such as moisture and drainage levels.
How do we describe soil texture structure and color consistence?
Soil texture refers to the composition of particles in the soil (sand, silt, clay). Soil structure refers to how those particles are organized (clumps, layers). Soil color is determined by its composition and can indicate fertility or drainage. Consistence refers to how easily the soil breaks apart or forms clumps when wet or dry.
Does soil reflect light?
No, soil does not reflect light well. Different types of soil can absorb and scatter light in different ways. Soil color is determined by the mineral content and organic matter, which affects how much light is absorbed or reflected.
Soil type is determined by the amounts of what?
Soil type is determined by the amounts of sand, silt, and clay particles present in the soil. These particles make up the soil texture, which influences drainage, water retention, and nutrient availability in the soil.
Describe three characteristics of soil?
Soil composition: Soil is composed of mineral particles, organic matter, water, and air. Soil texture: Soil can have different textures such as sandy, loamy, or clayey, which affect water retention and drainage. Soil pH: Soil acidity or alkalinity, as measured by pH, influences nutrient availability for plants and soil microbial activity.
What makes up a tornadoes color?
A tornadoes color is determined by how the light falls on it, and often the color of soil that it is lifting up.

How is a flowers color determined?
A flower's color is determined by the presence of pigments in its petals. These pigments are usually produced by the flower's genetic makeup and can be influenced by environmental factors such as soil pH and light exposure. Different pigments, such as carotenoids and anthocyanins, contribute to the wide range of colors seen in flowers.
Does soil reflect light?
No, soil does not reflect light well. Different types of soil can absorb and scatter light in different ways. Soil color is determined by the mineral content and organic matter, which affects how much light is absorbed or reflected.
How are babies eye color determined?
The eye color is determined by the genes of the parents.
Soil type is determined by the amounts of what?
Soil type is determined by the amounts of sand, silt, and clay particles present in the soil. These particles make up the soil texture, which influences drainage, water retention, and nutrient availability in the soil.
Is the color of a star determined by its location in the galaxy?
No. The color is determined by the star's temperature, not location.

What are the five color classes for surface soils?
The five color classes for surface soils are red, yellow, brown, black, and gray. These colors are determined by the amount of iron, organic matter, and other mineral content in the soil.
What is igneous rock color mainly determined by?
An igneous rock's color is mainly determined by its silica content.
Is hair color determined by the amount of keratin produced?
No, hair color is determined by the amount of melanin produced.
