Prediction of experimental results on additivity‐law failure

Prediction of experimental results on additivity‐law failure Experimental results on additivity‐law failure observed by direct brightness matching are estimated for various combinations of two spectrum colors. The estimations are made by using the prediction equation of the Brightness/Luminance (B/L) ratio effect on chromatic colors, which is based upon the Variable Chromatic Color (VCC) method for the effect. The predicted results confirm the existence of the two types of additivity‐law failures called enhancement or cancellation, already reported by several researchers. The prediction equation also clarifies that the effect of additivity‐law failure does not change for a wide change of adapting luminance used in observation. Both B/L effect and additivity‐law failure can be estimated quite nicely by the same prediction equation without making any modification to it. The Helmholtz–Kohlrausch effect can imply both effects in its wide definition. © 2000 John Wiley & Sons, Inc.

Abstract

Experimental results on additivity‐law failure observed by direct brightness matching are estimated for various combinations of two spectrum colors. The estimations are made by using the prediction equation of the Brightness/Luminance (B/L) ratio effect on chromatic colors, which is based upon the Variable Chromatic Color (VCC) method for the effect. The predicted results confirm the existence of the two types of additivity‐law failures called enhancement or cancellation, already reported by several researchers. The prediction equation also clarifies that the effect of additivity‐law failure does not change for a wide change of adapting luminance used in observation. Both B/L effect and additivity‐law failure can be estimated quite nicely by the same prediction equation without making any modification to it. The Helmholtz–Kohlrausch effect can imply both effects in its wide definition. © 2000 John Wiley & Sons, Inc. Col Res Appl, 25, 32–42, 2000
