Despite having difficulties in discriminating colors, individuals with a congenital color vision defect (CVD) sometimes identify colors correctly. One explanation for their correct use of the color name could be the context in which the color is used. In North America, how context influences the use of color names can be illustrated using the pedestrian signal light, where the color of the light indicating that it is safe to cross is white. Sixty color vision normals (CVNs) and 68 CVD subjects were asked to identify the color of the man figure icon from memory. All of the CVNs identified the figure correctly as white, whereas 56% of the CVDs identified the color of the man‐figure incorrectly, with 92% of the errors identifying the color as green and the remaining 8% as yellow. No one identified the figure as red. The data show one example of how context plays a role in how CVDs identify colors.

色觉不良者的经验:白色为绿色时

尽管很难区分颜色,但患有先天性色觉缺陷(CVD)的人有时仍能正确识别颜色。正确使用颜色名称的一种解释可能是使用颜色的上下文。在北美,可以使用行人信号灯来说明上下文如何影响颜色名称的使用,其中表示可以安全通过的光的颜色为白色。六十位彩色视力正常人(CVN)和68位CVD受试者被要求从记忆中识别出人形图标的颜色。所有CVN都将图形正确地识别为白色,而56%的CVD错误地将图形识别为颜色,其中92%的错误将颜色识别为绿色,其余8%的错误识别为黄色。没有人认为这个数字是红色的。
