There should be a high degree of contrast between the logo and its background.
Whenever possible, it is preferred that the Mattel Children's Hospital logo be used on a white background.
Due to visual color vibration between the gold shooting star and lighter background colors, the logo should not be used against backgrounds between 11% to 50% black. In these instances, place the full-color or black-and-white logo within a white background (such as a horizontal bar, a header or a footer). Also make sure that the containing shape meets minimum space requirements around the logo.
The reversed logo should be used against neutral backgrounds darker than a 50% value of black, or against 100% UCLA blue.
