The shield can be rendered in any color, but to change the color you must choose the correct shield file to begin. If you want the shield to be darker than the background, use the black shield file to change the color. If you want the shield color to be lighter than the background, use the white shield file to change the color.
Do not use the shield with any typography that essentially creates a new logo—a lockup used repeatedly for an extended period of time.
If you have questions about the use of the shield as art, please contact us.
Quick check: The black logo file uses a solid shield while the white logo file uses an outline for the shield.
Shield art files are located within the university logo bundle that downloads from brand.jhu.edu.
