| Abstract | Visualization is a powerful way to convey data, showing a great potential for joining and interrelating different data items. Nevertheless, when dealing with large amounts of data, visually merging different classes of informa-tion 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 col-ors. This approach, while generating an immediately perceivable way to represent merged items, keeps context through the association of the resulting color to its original provenience. We studied to which extent color blend-ing provides users with the means to understand the provenience of data items by conducting a user study with 73 subjects using CIE-LCh 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 blending intuitive. Results showed that people have difficulties in understanding blending of colors that are farther apart in the color wheel and indicated that the CMYK model may show promise for representing blended colors. |
