The ISCC-NBS System of Color Designation is a standardized method for naming colors. It combines a set of 13 basic color terms with a small set of adjective modifiers. This system was developed in the 1930s through a collaboration between the Inter-Society Color Council (ISCC) and the National Bureau of Standards (NBS). The goal was to create a color designation system that could be used across various fields, including science, art, and industry, and be understood by the general public. The system aims to provide a common language for describing colors in a standardized way.
Basic Color Terms
The system uses 13 basic color terms to categorize colors. These terms include hue, value, and chroma, which help in precisely describing a color.
- Hue: Refers to the color family, such as red, yellow, or blue.
- Value: Indicates the lightness or darkness of the color.
- Chroma: Describes the intensity or saturation of the color.
Adjective Modifiers
In addition to the basic color terms, the system uses adjective modifiers to further refine the color description. These modifiers help in specifying the exact shade or tint of the color.
- Modifiers: Include terms like "light," "dark," "brilliant," and "deep" to provide more detailed descriptions.
Applications
The ISCC-NBS System of Color Designation is widely used in various fields, including pharmaceuticals, textiles, and graphic design. Its standardized approach ensures consistency and clarity in color communication.
- Pharmaceuticals: Used in the United States Pharmacopoeia and the National Formulary for color designation.
- Textiles: Helps in maintaining color consistency in fabric production.
- Graphic Design: Provides a common language for designers to communicate color specifications.
