Answer 2

The three primary colors for road signs are red, yellow, and blue. These colors are chosen for their high visibility and the psychological impact they have on drivers.

Step-by-step explanation:

The three primary colors for road signs are red, yellow, and blue. These colors are fundamental in the color spectrum and cannot be created by combining other colors. Instead, they serve as the basis from which all other colors are derived. In terms of road safety, these primary colors are used due to their high visibility and the psychological impact they have on drivers, helping to convey important messages quickly and effectively. For instance, red often denotes prohibition or danger, yellow is used for caution, and blue usually provides informational cues. The selection of these colors for road signs follows a simplified theory of color vision, which states that there are three types of cones in the human eye, each corresponding to one of these primary colors.
