DEFINING COLOR TOLERANCES
A color tolerance is a limit to how big the difference in color between a sample and standard is allowed to be for the sample to be considered acceptable. Tolerance values should correlate to the human eye so that color is both visually and numerically acceptable.
To establish a color tolerance, the below steps should be followed:
1. Define a Color Standard: What Color Do You Want the Finished Product to Be?
2. Perform Visual Assessments: What Colors are Visually Acceptable?
3. Define Tolerance Values: What is the Range for Acceptability?
4. Establish a Tolerance System: Rectangular, Circular, or Elliptical?
