实验研究了颜色和亮度对比、对比方向和六个对比值对圆形表盘易读性的影响。四种色相的亮度与四种消色相匹配。色相以除色相和消色相外的所有可能的组合组合在一起，产生六个对比度值。在暗对明和明对暗对比方向上，对比度值相等。24名受试者中有一半接受过飞行员训练，另一半没有。道奇型速视镜显示刺激条件。阅读时间结果表明，在给定的消色差亮度对比值的表盘上添加颜色对比，在暗对比方向上添加浅色对比，不会降低表盘的可读性，并可能提高该表盘的易读性。易读性也随着对比度值的增加而增加。研究表明，颜色作为编码技术在复杂系统显示中的应用需要重新考虑。
An experimental study was conducted investigating the effects of color and brightness contrast, direction of contrast, and six contrast values upon the legibility of a circular dial. The brightness of four chromatic hues was matched with four achromatic hues. Hues were combined in all possible combinations excluding chromatic with achromatic, resulting in six contrast values. For both dark on light and light on dark contrast directions, the contrast values were equal. Half of the twenty-four subjects had pilot training and half did not. A Dodge type tachistoscope was used to present the stimulus conditions. Reading time results indicated that the addition of color contrast to a dial of a given achromatic brightness contrast value, with a light on dark contrast direction, will not degrade and may improve the legibility of that dial. Legibility was also found to increase as contrast value increased. The study indicates that the use of color should be reconsidered in its application as a coding technique in complex system displays.
