| 摘 要： | 为探究明度与色相同步变化时不同分级设色方案在数字环境下的适宜性，基于Munsell色彩调和秩序与CIEDE2000色差公式设计了7种分级设色方案，并开展了视觉认知试验。试验结果表明：①增加各级间色差会导致颜色辨识的准确性增强；②与各级间色差相等的色阶相比，色差先增大后减小的色阶有利于读图判别；③图斑面积分布均匀程度对颜色辨识的影响并不显著；④色阶的总色差增大，会导致颜色过渡的协调性降低。色差先增大后减小的色阶能产生较好的辨识效果，同时保持较好的色彩协调性，且相关规律可以推广到图斑面积分布均匀程度不同的地图中，在分级设色中运用具有优势。

| 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:①Increasing color distance will lead to higher accuracy of color recognition.②Compared with scales that has same color distance between classes,the first-increase-then-decrease scale results in better legibility.③The distribution of patch area has no significant effect on color recognition.④Increase 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. |
