I've told people for years that there is a psychology reason for the love of color. Not only does your favorite color say tremendous amounts about you but also can be used to your advantage. Why not? Others have been doing so for years.
You know the blue that so many companies use. The blue of Facebook, AT&T, Ford, HP, Samsung...yeah I could go on. This is supposed to give us the illusion of a good upstanding company with longevity, oh and trust.
Lawyers wear blue in the courtroom for the same reason and it's suggested that if you want that job chose blue, at least to accent what you wear. Yes, even in blue too much of a good thing is bad.
