I recently read Nora Reed’s blog post, Locate your Brand on the Color Spectrum, on Logoblog. Nora identified a trend, which you may have noticed from time to time, that some industries tend to congregate in a specific color scheme.

For example, fast food logos tend to be in the red/yellow category, while social networking sites predominately use blue for their logos. Similarly, I see many red and green pizza franchise logos. So why is this? Is it a tendency to imitate your competitor? Do these colors tend to create a particular feeling or notion that these brand owners seek? Or are these companies oblivious to the ability to differentiate their trademark through the use of color?
