Abstract

In some embodiments, a directional surface marking may provide directional messaging to users based on their direction of travel on a base surface, such as a roadway, walkway, or interior flooring, as non-limiting examples. In some aspects, the directional messaging may comprise different colors, text, or symbols, wherein a user may view different directional messaging on a directional surface marking dependent on direction of travel. In some embodiments, directional surface markings may comprise a profile layer, wherein the profile layer may comprise a plurality of profiles, which may provide a topography that allows for directional messaging utilizing surface colors on the topography.
