Shades designated as “1” and “1B” represent the darkest hues in many hair coloring systems. “1” typically signifies black, often with blue or cool undertones, while “1B” denotes off-black, generally appearing softer and containing warmer, brown undertones. Subtle yet significant, this distinction impacts how the color appears in different lighting conditions and against varied complexions.
Selecting between these seemingly similar shades can dramatically affect the final result. Accurately identifying the nuanced differences ensures a more natural and flattering look. This level of precision is paramount for professionals in the cosmetology industry and beneficial for individuals seeking at-home coloring solutions. Historically, the ability to achieve precise and consistent color has been a driving force in hair dye formulation, leading to the development of refined shade classifications like the “1” and “1B” distinction.
