Theoretical Analysis of Subtractive Color Mixture Characteristics V-Centroid of Subtractive Tristimulus Values

摘要

In additive color mixture,when more than two component tristimulus values are given then the mixture result is determined from a linear combination of the com-ponents.On the other hand,in subtractive color mixture,the resultant tristimulus values are not uniquely determined from component tristimulus values.Hence,analyses regard-ing the minimum and the maximum bounds are very impor-tant to understand the possible ranges of tristimulus values of subtractive color mixture.In our previous series of arti-cles,several theorems have been proven related to the bounds.In addition to the values,the centroid of a possible range is very important and essential to the prediction of subtractive color mixture.In the present article,several theorems related to the centroid are provided and proven.
