Why are airport runways black and not a colour that really stands out like pink?

Answer 1

This is due to the materials used. Asphalt and concrete tend to be dark or dull colors. You can’t paint the runways, because it would a) get slick as hell and b) the paint wouldn’t last very long with all the traffic. Some kind of pigment or dye would probably be impractical from a cost benefit perspective… runways are fairly visible already due to the size, and lights already do a pretty good job of increasing that visibility
