可视化是传达数据的一种强大方式，显示了连接和关联数据项的潜力。然而，在处理大量数据时，以可视方式合并不同类别的信息会带来几个挑战。然而，由于颜色对信息进行标记和分类的有效性，它可能是解决这一缺点的一种方法。合并具有不同颜色的项目可能会建议混合它们的原始颜色。此方法生成一种可立即察觉的方式来表示合并的项。它还通过将混合颜色与其原始颜色相关联来保持上下文。通过使用CIE-LCH、CMYK和HSV混合进行两项用户研究，以确定(I)人们能够在多大程度上在给定特定颜色的情况下理解其来源，以及(Ii)执行颜色混合的颜色模型，我们研究了颜色混合在多大程度上为用户提供了理解数据项的出处的手段。结果表明，CIE-LCH模型能更好地描述颜色混合，使用户更好地理解颜色的来源。
Visualization is a powerful way to convey data, showing potential for joining and interrelating data items. However, when dealing with large amounts of data, visually merging different classes of information poses several challenges. Color, however, due to its effectiveness for labeling and categorizing information, may be a solution to this shortcoming. Merging items with different colors may suggest mixing their original colors. This approach generates an immediately perceivable way to represent merged items. It also keeps context through the association of the mixed color to its original colors. We studied to which extent color blending provides users with the means to understand the provenience of data items by conducting two user studies using CIE-LCh, CMYK and HSV blending to ascertain (i) to which extent people are able to, given a particular color, understand its provenience, and (ii) the color model in which to perform color blending so that users find it intuitive. Results showed colors which are more suitable for blending so that users understand their provenience and indicated that the CIE-LCh model is more effective for representing color blending.
