Abstract

Abstract: This work is concerned with appropriate graded color schemes for area feature rendering in digital environment when the value and hue change simultaneously. We designed seven color schemes based on Munsell color harmony order and CIEDE2000 color difference formula, and a visual cognitive experiment was conducted. It is concluded that:① Increasing color distance will lead to higher accuracy of color recognition. ② Compared with scales that has same color distance between classes, the first-increase-then-decrease scale results in better legibility. ③ The distribution of patch area has no significant effect on color recognition. ④ Increase in color distance may decrease color coordination. The first-increase-then-decrease scale performs better while maintaining color coordination, which is recommended for graded color schemes. It also can be extended to maps with different uniformity of patch area.

Key words: graded color, color distance, color scheme, map patches, visual cognitive experiment
