I’ve selected the Qatar Airways logo as an example of similarity from Gestalts Principles of Design. This example is a little more subtle, I paid extra close attention to what’s within the maroon part of the image. The white lines coming in from the right off the image resemble similarities to the grey in the background portion. Both the lines in each section of the image present a strong sense of movement, presented with the white background as if the animal is running. It helps to distinguish that this is an airline logo.
