That depends on what type of clay it is. The most common type of clay in the US southwest, where I'm from, is red clay. Red clay forms from the breakdown of rock in the soil over hundreds of years. It gets its red color from iron oxide. Other than this, clay can be many different colors ranging from grey to orange-red. Common colors include grey, brown, green, blue, yellow, and near-black.

Loam is a soil type that typically has a dark brown color due to the organic matter content.
The 15 types of soil are clay soil, sandy soil, silt soil, peat soil, loam soil, chalky soil, saline soil, acidic soil, alkaline soil, silty soil, black soil, red soil, laterite soil, desert soil, and loess soil.
Clay loam soil typically needs more liming compared to sandy loam, loam, and silt loam soils. This is because clay loam soil has a higher proportion of clay particles, which can lead to greater acidity and compaction issues that benefit from liming to improve soil quality.
Gram seeds require loam soil to grow because loam soil provides good drainage, aeration, and moisture retention, which are essential for the healthy growth of gram plants. The balanced mixture of sand, silt, and clay in loam soil ensures that the roots can easily penetrate the soil to access nutrients and water.
Soil with equal parts of clay, sand, and silt is called loam soil. Loam soil is considered to be the best type of soil for plant growth because it has a good balance of drainage, moisture retention, and nutrient availability.
