Black is more than just darkness. It’s a critical design element that signals quality, premium perception, and brand value. Yet accurately evaluating black has long been a challenge. Brightness alone can’t fully describe its appearance; hue and undertone are equally important, making traditional L*, a*, and b* assessments complex and inconsistent, especially for deep-black materials. This application note introduces a new approach to black evaluation. By consolidating Blackness, Jetness, and Undertone into a single unified index, Konica Minolta provides a practical, objective, and repeatable way to assess black quality. The result is a clear standard that reduces subjective interpretation and enables reliable quality control across production and design.
