Lisa, no offence taken -- I just find people's differing perceptions very interesting. I've noticed that a lot of people have those associations to blue and that makes sense -- it is, after all, the colour of many military and police uniforms and flight attendants' uniforms and suits...so I get why people see it as a conservative choice.
Blue is my black, though -- the backdrop to everything -- which I guess could be the definition of mainstream, in some ways.
Remember how some of the Pantone colours never seemed to make it to retail? In this case, we'll probably never know whether the colour takes off because there is so much of it available already, ha ha!!
