An Alternating Sequence
If there are less than four balls on a wire, they should all be this garish shade of orange. Longer lines with more balls, on the other hand, may benefit from a color pattern to guarantee that at least one of them gets the pilot’s attention.
Engineering Discoveries
The majority of these sequences alternate between orange, white, and yellow. However, it is still essential to adapt the choice of color to the surroundings of the marker to make them more visible to the aircraft pilots.
