Does color affect you ability to read them? (for example: light on dark, dark on light, specific colors, . . .)

Highway engineers have been concerned about this question for a long time because road signs have to be read as quickly as possible by motorists. Although the human eye is most sensitive to colors near green, the contrast between the writing and the background has been found to be more important. So, it does not matter whether you have got light on dark or dark on light, you just do not want dark on dark or light on light.
