What is the recommended color scheme for pedestrian signals?

The recommended color scheme for pedestrian signals consists of green for "walk" and red for "don't walk." This color coding is standardized in many traffic control guidelines to ensure clarity and consistency across various jurisdictions. The use of green for "walk" indicates that it is safe for pedestrians to cross the street, while red for "don't walk" clearly signals to pedestrians that they should not begin crossing. These colors are widely recognized and are intuitive for most people, helping to prevent confusion and enhance safety for pedestrians at intersections.

The other choices, while they suggest different color combinations, do not adhere to these established conventions, which are designed to create uniformity and understanding of pedestrian signals across different locales.
