This is the logo of World Wide Life organization. It is a smart choice to use panda as the logo, since panda is already black and white. The panda’s back line is not filled by black, and just leaved it white. All the parts of panda’s body are shaped in the same way.
The color matches Barbie well. And the shape of this doll is just like font.
This is the logo of Target. The color and the design are pretty simple, but it perfectly shows the brand.
