This shade typically represents a dark brown hue, often described as rich or deep. It sits between a lighter brown (level 4) and near-black shades (level 2). Visual aids, such as color charts or photographs of hair swatches, frequently accompany descriptions to provide a precise visual representation. This numerical classification system provides a standardized language for discussing and selecting specific shades, crucial for consistent results in professional settings.
Standardized color numbering systems allow for clear communication and accurate color matching between manufacturers, stylists, and clients. This precision minimizes the risk of miscommunication and ensures predictable outcomes. Historically, achieving consistent color results was challenging due to variations in dye formulations and subjective descriptions. Modern systems offer greater control and predictability, benefiting both professionals and consumers. A thorough understanding of this system enables informed choices regarding hair color products and services.
