White tolerance study by N.Na

Nooree Na, a Ph.D. candidate of CED Lab published a paper entitled as “Color tolerance study on white in practical aspect: Perceptibility versus acceptability” in Color Research & Application. Two master students, Kyungah Choi and Jeongmin Lee co-authors. This study¬†investigates how the color tolerance for whites is affected by color category and context: color categories refer to hue segments, and context refers to perceptibility in comparison with acceptability.


This study investigates how the color tolerance for whites is affected by color category and context. Two experiments with different contexts, perceptibility or acceptability, were conducted using 27 color variation samples from 6 color categories (Neutral-White, Red-White, Yellow-White, Green-White, Blue-White, and Blue-Vivid). The results indicated that the color tolerance for Green-white is dominantly higher relative to the other white-based colors, whereas the color tolerance for Yellow-White and Neutral-White are relatively lower. However, contrary to the hypothesis, no significant differences in the level of color tolerances could be found between the two context of perceptibility and acceptability. The color tolerance thresholds for each color category groups in both experiments were similar.
