基于红绿色觉异常人群的路况地图色彩设计研究

红绿色觉异常人群对于明度变化的感受比正常视觉者更加敏感,可以弥补色相辨别的缺陷。通过针对黄色明度对比实验得出红绿色觉异常人群对明度对比各等级的视觉感受,找出对红绿色觉异常人群既可以容易识别又不会觉得刺眼的明度对比范围。实验结果引入地图设色,结合色彩象征意义,做出红绿色觉异常人群和正常人群通用的路况地图。在路况信息清晰表达前提下,尽可能保留色彩象征意义,并保证地图的观赏性。通过路况地图色彩明度对比实验制作出红绿色觉异常人群既能无障碍识别又带有警示象征意义的路况地图。

The Road Condition Map Color Design aiming at Red and Green Color Vision Impaired People

Compared with the normal vision people ,the red and green color vision impaired people are more sensitive to brightness contrast ,which can remedy the defect of hue distinguish .Through the yellow brightness contrast experiment ,this paper conclude the visual perception of each scale brightness contrast for those people . The brightness contrast range that those people can easily identify and do not feel dazzlingly bright .The experimental results are provided with the color design of map ,combined with color symbolism ,and the universal road condition map is designed for red and green color vision impaired people and normal vision people .On the premise of traffic information being expressed clearly ,the color symbol is kept ,through brightness contrast experiment a universal road conditions map is proposed .
