Quizplus · Accepted Answer

The color of an object depends on the color of the light it reflects. In this scenario, the atmospheric gases are red, which means that the light that reaches the eyes of an observer is already tinted red. For distant dark colored hills to look a different color, they should reflect light with a complementary color to red (opposite in the color wheel), which is green. However, none of the choices have green as an option. Therefore, the closest option is D, reddish, because the hills will reflect some of the red light that reaches them, and that will mix with their own color, making them appear reddish.
