Portland Orange is the color of light emitted by the dont walk phase of pedestrian crossing signals in the United States and Canada. The color was chosen to avoid confusion with regular traffic lights in conditions of poor visibility. Its chromaticity is specified by the Institute of Transportation Engineers in that body's technical standards, along with for the walk lights. Its application is stipulated in the U.S. federal Manual on Uniform Traffic Control Devices. Various jurisdictional standards also require Portland Orange for dont walk signs.
