What is the color of the path of travel stripping from a curb ramp to the pedestrian access of trash enclosure?
If you're talking about a:
PEDESTRIAN WAY. A route by which a pedestrian may
pass.
Then I don't know of any requirements for color at the state code level. There might be something at the local level though.
If you're talking about an access aisle, then:
11B-502.3.3 Marking. Access aisles shall be marked with
a blue painted borderline around their perimeter. The
area within the blue borderlines shall be marked with
hatched lines a maximum of 36 inches (914 mm) on center
in a color contrasting with that of the aisle surface, preferably
blue or white. The words "NO PARKING" shall be
painted on the surface within each access aisle in white
letters a minimum of 12 inches (305 mm) in height and
located to be visible from the adjacent vehicular way.
Access aisle markings may extend beyond the minimum
required length.
An access aisle is defined as:
ACCESS AISLE. [DSA-AC] An accessible space adjacent to
or between vehicle spaces that provides clearances in
compliance with this code.
