Delta E recipe match prediction

A method of determining a color formulation for a target color begins to generate a plurality of candidate color formulations to reproduce the target color. For each candidate formulation, a predicted delta E indicative of the difference between the predicted color of the candidate formulation and the target color is determined. And for each candidate formulation, the predicted confidence value in delta E is generated by summing the weighted figure of merit of each colorant in the candidate formulation. The weighting of the figure of merit represents the proportion of each colorant in the candidate formulation. The formulation is then selected based on the predicted delta E and a confidence value. The target color may be defined according to a multi-dimensional color space. 一种确定目标颜色的颜色制剂的方法以生成多种候选颜色制剂以再现目标颜色开始。对于每种候选制剂，确定指示候选制剂的预测颜色与目标颜色的差异的所预测德尔塔E。而且对于每种候选制剂，所预测德尔塔E中的置信度值通过对候选制剂中每种着色剂的加权品质因数求和而生成。品质因数的加权表示每种着色剂在候选制剂中的比例。然后，基于所预测德尔塔E和置信度值选择制剂。目标颜色可以依据多维颜色空间来定义。
