Portland Orange is the color of light emitted by the phase of pedestrian crossing signals in the U.S. and most of Canada. Its chromaticity is specified by the Institute of Transportation Engineers in that body's technical standards,〔(ITE Pedestrian Traffic Control Signal Indications standard )〕 and its application is stipulated in the U.S. Federal Manual on Uniform Traffic Control Devices.〔(MUTCD Section 4E.01 )〕 Various jurisdictional standards also require Portland Orange for don't-walk signs.〔(Cincinnati, Ohio traffic signal requirements )〕 ==International application== Portland Orange is generally not used outside the United States and Canada, and is not seen in Quebec. In most of the world, red is used for the symbol instead of Portland Orange.
