Many professional workers such as engineers and designers must read and comprehend graphics in the workplace. Many studies have analyzed the effects of background color when reading text, but few have studied its effects when reading graphics.
This study examines how different screen polarities and background colors can influence the reading and comprehension of graphics.
504 participants were selected by convenience sampling and divided into 14 groups. The experiment was performed in three parts. Parts 1 had 2 groups; Parts 2 had 6 groups; Parts 3 had 6 groups. Each group had 36 participants.
In each of the three parts of this study, a combination of black and white graphics was used as a background. Three experiments were performed. Color was the independent variable; accuracy in reading/comprehending graphics was the dependent variable.
Experiment One showed that test participants performed better in positive (black on white) graphics test than in negative (white on black) graphics test on the computer screen. Experiment Two showed that screen background colors also significantly affect the accuracy of graphics reading/comprehension on the computer screen. Experiment Three showed that performance improved when the color of the computer screen polarity was adjusted.
Screen polarity can affect the accuracy of graphics reading/comprehension; screen background color affects the accuracy of graphics reading/comprehension; adequate background color as a contrast increases experiments the accuracy of graphics reading/comprehension.
许多专业工作者，如工程师和设计师，在工作场所必须阅读和理解图表。许多研究分析了阅读文本时背景颜色的影响，但很少有研究探讨其在阅读图表时的影响。
本研究考察不同的屏幕极性和背景颜色如何影响图表的阅读和理解。
通过便利抽样选取504名参与者，分为14组。实验分三个部分进行。第一部分有2组；第二部分有6组；第三部分有6组。每组有36名参与者。
在本研究的三个部分中，均使用黑白图表组合作为背景。进行了三项实验。颜色为自变量；图表阅读/理解的准确性为因变量。
实验一表明，测试参与者在电脑屏幕上对正片（白底黑字）图表测试的表现优于负片（黑底白字）图表测试。实验二表明，屏幕背景颜色也显著影响电脑屏幕上图表阅读/理解的准确性。实验三表明，调整电脑屏幕极性的颜色时，表现会有所提高。
屏幕极性会影响图表阅读/理解的准确性；屏幕背景颜色会影响图表阅读/理解的准确性；适当的背景颜色作为对比可提高图表阅读/理解的准确性。
