Which color background is used for the photos of adults on Oregon IDs?

The background color used for photos of adults on Oregon IDs is blue. This consistent use of blue helps to standardize the identification process, making it easier for law enforcement and others to recognize and verify the authenticity of the ID. The blue background provides good contrast for facial recognition and is designed to enhance the overall appearance of the identification, thereby reducing the potential for fraudulent activity. Government-issued IDs often have specific design elements, including background colors, to maintain security and integrity, and in this case, blue is the chosen color for adult photos on Oregon IDs.
